Abstract：

Herein,　a　series　of　environmentally　friendly　rare　earth　doped　yellow　pigments　with　near-infrared　(NIR)　properties　were　synthesized　using　solid-state　reaction　at　a　high　temperature　of　1200　°C,　with　the　general　formula　Y2−xBixMoO6.　The　prepared　pigments　were　characterized　using　analytical　techniques,　such　as　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　CIE　1976　color　space　system,　ultraviolet–visible/near　infrared　(UV–Vis/NIR)　spectroscopy.　Results　indicated　that　its　color　changes　from　white　to　yellow　after　doping　with　Bi2O3　in　Y2MoO6.　As　the　doping　amount　of　Bi　increased,　the　yellow　color　gradually　deepened.　All　the　doped　samples　exhibited　a　monoclinic　structure　with　space　group　C2/c　(15).　When　the　optimal　doping　ratio　was　Y1.8Bi0.2MoO6　(i.e.,　x　=　0.2),　the　NIR　reflectance　(R%)　and　NIR　solar　reflectance　(R∗%)　of　the　pigment　sample　both　exceeded　100　%.　In　the　study　of　acid　and　alkali　resistance,　the　color　difference　value　ΔE∗　before　and　after　pigment　soaking　was　less　than　5,　indicating　good　chemical　stability.　In　the　coating　study,　the　temperature　difference　between　the　air　inside　the　pigment-coated　house　model　and　the　air　inside　the　uncoated　house　model　reached　7　°C　after　20　min　of　irradiation　using　an　infrared　lamp,　suggesting　that　the　prepared　pigment　reflects　solar　thermal　radiation　well　and　demonstrates　good　thermal　insulation　performance.　©　2025　Elsevier　Ltd　and　Techna　Group　S.r.l.
