  • 摘要

    采用Czochralski法生长出了ZnWO4∶Sm3+单晶(Sm2O3=0.1wt%)，测量了晶体的吸收光谱.利用激光Raman谱仪在He-Ne激光器632.8nm波长激光激发下，观测到448，471，505，533nm的上转换锐线荧光，对其发光机理进行了探讨.

     

    Abstract

    The ZnWO4∶Sm3+ single crystal (Sm2O3=0.1wt%) has been grown by the Czochraiski technique. Absorption spectra were measured. The up-conversions at 448,471,505 and 533nm were observed by exciting with a He-Ne laser at 632.8nm wavelength, using a laser Raman spectrometer.
