【摘要】 根据ErP₅O₁₄的吸收和荧光光谱,用Judd—Ofelt理论计算了在此晶体中Er³⁺的强度参数Ω_λ（或τ_λ）,由此计算了激光能级辐射跃迁速率、辐射寿命、荧光分支比和积分发射截面等光谱参数。提出了在Peap与强度参数的总和之间存在直线关系的经验公式。讨论了ErP₅O₁₄作为激光材料的可能性。更多还原

【Abstract】 Intensity parameters Ωλ(or τλ) of Er3+ in crystal ErP5O14 were calculated by Judd-Ofelt theory. With these Ωλ valus, the oscillator strength, spontaneous radiative transition rate,seadiative lifetime, branching ratio and integrated emission cross section were calculated. In comparison with integrated emission cross section of certain laser crystals such as YAlO3:Er3+ and-CaF2:Er3+, the potential application of ErP5O14 as laser material was discussed.更多还原
