摘　　要：本文探讨了助熔剂法生长 YVO_4:RE^(3+)(RE:Pr,Sm,Tb,Er,Dy)晶体的工艺。讨论了助熔剂 V_2O_5,Pb_2P_2O_7和温度对晶体生长习性和缺陷的影响。测定了晶体的结构参数和光谱。Y_(0.9)Sm_(0.1)VO_4和 Y_(0.95)Dy_(0.05)VO_4晶体具有很好的光谱特性。in this paper the technique of YVO_4:RE^(3+) (RE:Pr,Sm,Tb,Er,Dy) crystal growth has been studied by flux method.The influence of V_2O_5,Pb_2P_2O_7 flux and temperature of crystal growth on the crystal behaviour anddefects has been discussed.The crystal structure and spectra have been mea-sured and analysed.It is found that there is of excellence properties of spe-ctra in the Y_(0.3)Sm_(0.1)VO_4 and Y_(0.95) DY_(0.05)VO_4 crystals.
