The luminescence energy transfer or diffusions were limited by the long distances between Er<sup>3+</sup> ions, which are based on a special structure.
A novel green up-conversion luminescence material, K<sub>3</sub>LaTe<sub>2</sub>O<sub>9</sub>:Er, was synthesised <italic>via</italic> a solid-state reaction method.
Abstract The thermal effects of Er/Yb‐doped NaYF 4 phosphor induced by 980/1510 nm laser diode irradiation were intuitively and contrastively investigated using an infrared imaging technology with real‐time online monitoring. Yb 3+ /Er codoped materials have strong high‐temperature elevation under 980 irradiation. However, the severe higher Er ion doping concentration are remarkably attributed to cross relaxation between ions energy transfer in /Yb ‐codoped also contributes 1510 Under same...
The thermal effects of NaYF<sub>4</sub>:Er microcrystals under 1550 nm laser diode irradiation were investigated using an infrared imaging method.
Lanthanide ions have abundant excited-state channels which result in a radiation relaxation process generally accompanied by non-radiation process. However, processes will consume the activation energy and reduce luminescence efficiency of phosphor. Two lasers with an excitation matched ground state absorption excited were used to excite phosphors avoid This approach can achieve purpose populating specific states lanthanide ions, furthermore effectively tunes intensity color output sample....
The Yb 3+ and Er co-doped yttrium molybdenum oxide upconversion phosphors were prepared by the solid state combustion method using urea as fuel at ignition temperature of 550 °C. characterized X-ray diffraction (XRD), scanning electronic microscope (SEM), photoluminescence spectra. XRD results revealed samples pure monoclinic Y 2 Mo 4 O 15 phases when sintering was 700 SEM micrographs illustrated particle size distribution almost uniform with an average diameter about 0.5–1.0 m. obtained :Yb...

High-crystallized Y 2 O S suspension was synthesized by a novel two-step method of high temperature solid-state reaction and subsequent colloidal processing. The synthesis proposed in this study retains all advantages the method. obtained data agrees with that PDF card, which indicates product is pure crystals. results show prepared particles are highly crystallized without any significant defects. fine smooth were almost regular, exhibiting an approximately subspherical shape. Quantitative...
