采用提拉法在不同气氛下生长了尺寸为18 × 18 × 16 mm 3的TbVO 4（TV）单晶。XPS研究表明，在99.9%N2气氛下生长的TV晶体中存在V4+和Tb 4+离子，在透射光谱中产生了一个中心位于950 nm的宽吸收峰。在80%N_2 + 20%CO_2混合气氛下生长的TV晶体在600-1500 nm波段具有较高的透过率。测量了电视晶体的法拉第旋转谱。在500-1500 nm波段，TV晶体比TGG晶体具有更大的法拉第旋转。
TbVO4(TV) single crystals with dimensions of 18 × 18 × 16 mm3were grown by Czochralski method under different atmosphere. XPS studies revealed the presence of V4+and Tb4+in TV crystal grown at 99.9% N2atmosphere, which caused a wide absorption peak centered at 950 nm in the transmission spectrum. TV crystal grown at 80% N2+ 20% CO2mixed atmosphere has high transmittance at 600–1500 nm waveband. Faraday rotation spectra of TV crystal were measured. TV crystal has a larger Faraday rotation than terbium gallium garnet (TGG) crystal at 500–1500 nm waveband.
