摘要
利用J O理论计算了Er3 + 掺杂的氟氧化物玻璃材料MFT的光学性质 ,得到了一些能级间跃迁的振子强度、跃迁几率、分支比、及寿命等数据。并通过实验测量了吸收光谱、激发光谱和发射光谱等。
The J O theory used to calculate optical properties of Er 3+ in oxide fluoride glass,the oscillator strengths,transition probabilities,branching ratios and the lifetimes were obtained.The absorption spectra,emission spectra,and excitation spectra were measured. We present a preparation method of fluoride oxide glass (MFT) containing TeO\-2,PbF\-2,AlF\-3,BaF\-2,NaF,doped with Er\+\{3+\} ions.The impurity concentration of Er\+\{3+\} in this sample is 2mol%.Based on the J O theory the optical transition properties were calculated using the absorption spectra data.The J O parameter Ω 2,Ω 4,Ω 6 are 1 637E 20,0 225E 20,0 480E 20,respectively.The oscillator strength ,transition probabilities,the branching ratios and radioactive transition lifetimes were obtained.The calculated results are analogous with experimental observation.The excitation spectra were measured at 550 and 660nm.The emission spectra were measured under different excitation wavelength related to the excitation spectra.
