摘要
采用TSSG法生长出尺寸为30mm×15mm×10mm的KYb（WO4）2晶体，XRD分析表明为低温相的KY-bW晶体，计算其晶格常数为a=10．61A°，b=10．295A°，c=7．495，β=130．65°。测得样品的红外和拉曼光谱，结果表明KYbW晶体有较强的拉曼活性，钨氧双桥键WOOW和单桥键WOW基团的振动在200—1000cm^-1范围内，对峰值与相应的振动进行了指认。
KYb （WO4）2 crystal sized 30mm × 15mm × 10mm has been grown by TSSG method. It was identified as β - KYbW crystal by XRD analysis, and the cell parameters of KYbW were calculated ： a = 10.61A°, b = 10. 29A°, c =7.49A°, β = 130. 65°. Infrared spectrum and Raman spectrum of the sample were measured, which showed that KYbW is a Raman active medium. The Raman peaks caused by bridge bond of WOOW and WOW were at 200 - 1000cm^-1, and the vibrational frequencies and Raman active modes for KYbW were assigned.
