| 摘 要： | 采用Czochralski法生长出ZnWO4:Er3+(Er=0.02mol)单晶,测量了吸收光谱和激发光谱。在波长966nm功率500mW的激光二极管(LD)激发下观察到上转换发光。强度最大的发射峰位于547和558nm,发射光谱分析表明,上转换激发过程与双光子步进吸收有关。

| Abstract: | Single crystals of ZnWO4: Er3+(Er:0.02 mol) have been grown by the Czochralski method and their absorption and excitation spectra are measured. It is observed that the up conversion luminescence phenomenon in the crystals by laser diode(LD)excited with 500 mW power at 966 nm wavelength. The most strong fluorescence intensity are occurred at 547 and 558 nm wavelength. Studies on emission spectra shown that the excitation process of upconversion luminescence relatives to the stepwise two photon absorption. |
