Abstract ：
In this work, a ligand-free luminescent hydrogel is used as a visual ratiometric fluorescence sensor to detect rare-earth (RE) ions for the first time. This hydrogel is easy to be prepared, environmentally friendly, and has high luminescent efficiency. It is found that the fluorescence intensity and emission color of the hydrogel immediately change significantly when solution of active RE3+ ions is added without any treatment. According to the linear relationship between the fluorescence intensity ratio and the concentration of RE3+ solutions, the detection limit is calculated to be as low as 0.94 μM. The detection of RE ions has strong anti-interference to other ions. Therefore, this sensor can be used for preliminary field exploration of RE ores and detection of waste containing small amounts of RE ions. © 2024 Elsevier B.V.

Abstract ：
In this paper, a very simple method was used to synthesize ligand-free luminous hydrogels doped with Tb3+ and Eu3+. The hydrogels exhibit red (615 nm), green (544 nm) and blue (425 nm) emissions derived from Tb3, Eu3+ and defects, respectively. Effective energy transfer from Tb3+ to Eu3+ is observed. We apply these ligand-free luminous hydrogels for temperature sensing for the first time. In surprise, the relative sensitivities are all very high (>2 %/K) by using many kinds of fluorescence intensity ratios. In addition, with the increase of temperature, the emission color of the samples changes significantly (from orange-red to blue) which can be applied for visual temperature sensing. The above results infer that the ligand-free luminous hydrogels can be used as an eco-friendly visual temperature sensing material. © 2024 Elsevier B.V.

The temperature-dependent emission spectra and the fluorescence decay curves of samples show the quantum dots can be applied to dual-mode temperature sensing employing fluorescence intensity ratio technique (between 656 nm (Sm3+) and 549 nm (Tb3+)) and fluorescence lifetime thermometry (549 nm (Tb3+)), achieving maximal relative sensitivities of 3.24%/K (351 K) and 0.68%/K (373 K), respectively. This study offers valuable insights into the temperature sensing capabilities of these quantum dots, which shows that these quantum dots are promising high-sensitivity dual-mode temperature sensing materials. © 2024 Elsevier Ltd

Abstract ：
Fluorescence fluctuation-based super-resolution microscopy (FF-SRM) is an economical and widely applicable technique that significantly enhances the spatial resolution of fluorescence imaging by capitalizing on fluorescence intermittency. However, each variant of FF-SRM imaging has inherent limitations. This study proposes a super-resolution reconstruction strategy (synSRM) by synergizing multiple variants of the FF-SRM approach to address the limitations and achieve high-quality and high-resolution imaging. The simulation and experimental results demonstrate that, compared to images reconstructed using single FF-SRM algorithms, by selecting suitable synSRM routes according to various imaging conditions, further improvements of the spatial resolution and image reconstruction quality can be obtained for super-resolution fluorescence imaging. © 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

Abstract ：
It can promptly detect hot-spot in the operation of the generator by real-time monitoring of the operating temperature of the windings in the hydromotor, thereby ensuring the safe operation of the hydromotor. To overcome the limitation of the sensing temperature measurement distance of the down-conversion fluorescence optical fiber temperature sensor does not exceed 30 meters, a method was proposed to use a semiconductor laser with the wavelength of 1550nm which was a low loss in optical fiber as the excitation source to generate upconversion fluorescence for an optical fiber temperature sensor. Upconversion materials ZnF2: Er3+, Yb3+ were selected as the fluorescent materials for the sensor. An experimental device was constructed, and the upconversion-fluorescence lifetime and the temperature were tested and calibrated. The results showed that the optical fiber temperature measurement distance of this method can reach to 76 m, meeting the demand for the temperature monitoring of the hydromotor windings. © The Authors.

Abstract ：
The thermal ablation and the cutting tissue for tumors with laser surgery are very important in nowadays medical surgery. Therefore, the real-time monitoring of the scalpel temperature has become the focus technical research. In this paper, a laser fiber scalpel temperature measurement system based on the intensity peak ratio of upconversion fluorescence excited by 980nm laser was designed, and a type of upconversion fluorescent material was demonstrated and applied to the optical fiber scalpel, so that the accuracy and safety of surgical temperature measurement can be improved. This paper firstly analyzed the principle of upconversion fluorescent temperature measurement. Secondly, the preparation of the fluorescent material was introduced and the CaWO4: Er3+, Yb3+ was placed in a quartz tube to make a fiber-optic sensing probe, and the fluorescence intensity peak ratio(FIR) temperature measurement was carried out by warming up (up to 800℃), cooling down, and warming up again to calibrate the relationship between the temperature and the FIR, and the fourth-order expression of the FIR with the temperature was obtained. The fluorescent material was combined with the optical fiber scalpel tip, which was used to improve the accuracy and safety of surgery by changing the power of the laser. Then, the fluorescent material was combined with the scalpel tip, and the laser optical fiber scalpel was heated by increasing the power of the 980nm laser. Finally, the FIR thermometry value was calibrated with the temperature to obtain the laser power-temperature equation, and the temperature accuracy was ensured by multiple measurements to realize the real-time monitoring of the temperature of the optical fiber scalpel in the process of optical fiber laser surgical scalpel(OFLSS). © The Authors.
