It is absolutely imperative for development of material science to adjust upconversion luminescence (UCL) properties of highly doped upconversion nanoparticles (UCNPs) with special optical properties and prominent application prospects. In this work, featuring NaHoF4@NaYbF4 (Ho@Yb) structures, sub‐30 nm core–multishell UCNPs are synthesized with a small NaHoF4 core and varied Gd3+/Yb3+ coexisting...
Y2O3:Sm and Gd2O3:Sm powder phosphors were prepared by carbonate coprecipitation method. The purified crystalline phases of Y2O3:Sm and Gd2O3:Sm were obtained at 600°C, and the crystallinity increases with increase in annealing temperature. Both samples contain aggregated phosphor particles. An energy transfer (ET) from Y2O3 and Gd2O3 hosts to sm3+ has been observed, and the ET efficiency in the latter...
