【摘要】 用提拉法(CZ法)生长出大尺寸、光学质量好的Er3+:Y0.5Gd0.5VO4单晶.在室温下,测量Er3+:Y0.5Gd0.5VO4晶体的吸收光谱、荧光光谱以及上转换荧光;利用Judd-Ofelt理论计算了Er3+离子在Y0.5Gd0.5VO4晶体中的振子强度P JJ′、自发辐射跃迁几率AJJ′和激发态荧光寿命τJ等光谱参数,在此基础上得出了Er3+:Y0.5Gd0.5VO4晶体的光学特性.
【Abstract】 Er3+:Y0.5Gd0.5VO4 single crystal with large size and good optical quality has been grown by Czochralski method.Its absorption and emission spectra were measured at room temperature.The absorption cross-sections are calculated on the basis of its spectra.According to Judd–Ofelt theory,the phenomenological intensity parameters ?λ of Er3+ ionshave been fitted adopting least-squares method.Moreover,the spectral parameters of Er3+ ions including oscillator strengths,radiative transition probabilities,radiative lifetimes and integrated emission cross-sections have been calculated.From the parameters mentioned above,the laser emission probability of Er3+:Y0.5Gd0.5VO4 crystal was discussed.
