Abstract：

Fluorescence　spectra　of　Tm3+-doped　silica　glass　microspheres　under　excitation　of　a　continuous　wave　diode　laser　at　1527　nm　were　investigated.　It　showed　rich　upconversion　emissions　from　the　high-energy　states　of　Tm3+　ions,　which　spanned　from　the　ultraviolet　(UV)to　near-infrared　(NIR).　Analysis　indicated　that　the　purple　light　emission　came　from　a　six-photon　upconversion　process.　What＇s　more,　a　broadband　fluorescence　emission　was　observed　in　a　wavelength　range　of　620–935　nm.　The　high　power　density　was　a　main　advantage　by　confining　the　light　in　the　microsphere　cavities.　The　multiple　fluorescence　upconversion　emissions　of　Tm3+-doped　silica　glasses　under　∼1550　nm　excitation　may　open　a　new　door　to　explore　the　future　visible　light　communication　technology.　©　2019　Elsevier　B.V.
