【摘要】 采用高温熔融法制备了掺杂不同稀土氧化物(Pr₆O₁₁,Ho₂O₃,Dy₂O₃)的Ga₂O₃-B₂O₃-ZnO-TiO₂-Tb₂O₃玻璃。研究了掺杂不同稀土氧化物对Ga₂O₃-B₂O₃-ZnO-TiO₂-Tb₂O₃玻璃的结构、物理性质、光学性质和磁光性质的影响。掺杂不同稀土氧化物后，玻璃的密度、折射率和Verdet常数均有所增加。随着入射光波长和温度的增加，玻璃的Verdet常数的绝对值逐渐降低。在温度为298.15 K、入射光波长633 nm的条件下，当Tb₂O₃和Ho₂O₃的掺杂摩尔分数分别为40%和1%时，玻璃的Verdet常数达到-156.45 rad/（T·m），高于商用的Tb₃Ga₅O₁₂晶体（-134 rad/（T·m））；温度为298.15 K和入射光波长为515 nm时，玻璃的Verdet常数达到-189.80 rad/（T·m），这表明其在光电功能材料领域具有潜在的应用价值。更多还原

【Abstract】 Ga₂O₃-B₂O₃-ZnO-TiO₂-Tb₂O₃ glasses doped with different rare-earth oxides(Pr₆O₁₁,Ho₂O₃,Dy₂O₃) were prepared using the high-temperature melting method.The effects of doping different rare-earth oxides on the structure,physical properties,optical properties,and magneto-optical properties of Ga₂O₃-B₂O₃-ZnO-TiO₂-Tb₂O₃ glasses were studied.After doping with different rare-earth oxides,the density,refractive index,and Verdet constant of the glass all increase.As the wavelength of incident light and temperature increase,the absolute value of the glass’s Verdet constant gradually decreases.At a temperature of 298.15 K and an incident light wavelength of 633 nm,when the doping amounts of Tb₂O₃ and Ho₂O₃ were 40%and 1%respectively,the Verdet constant of the glass reached -156.45 rad/（T·m）,which is higher than that of the commercial Tb₃Ga₅O₁₂ crystal（-134 rad/（T·m））.At a temperature of 298.15 K and an incident light wavelength of 515 nm,the Verdet constant of the glass reached -189.80 rad/（T·m）,indicating its potential application value in the field of optoelectronic functional materials.更多还原
