【摘要】 根据Ｔｍ３＋离子的吸收光谱，计算了在氟锆酸盐玻璃中Ｔｍ３＋的Ｊｕｄｄ－Ｏｆｅｌｔ参数和红外跃迁３Ｆ４→３Ｈ４，３Ｈ４→３Ｈ６和３Ｆ４→３Ｈ５的自发跃迁几率，研究了Ｔｍ３＋的红外发射光谱和它的交叉弛豫过程，讨论了离子浓度对红外发光强度的影响，并计算了这些跃迁的发射截面．更多还原

【Abstract】 In the work, we have calculated Judd Ofelt parameters and the spontaneous emission probabilities of the transitions 3F 4→ 3H 4, 3H 4→ 3H 6, and 3F 4→ 3H 5, according to the absorption of Tm 3+ in the fluorozirconate glass. The three infrared emission spectra of Tm 3+ and the cross relaxation have beem investigated. The effect of the Tm 3+ concentration on the infrared emission intensities has been discussed. The emission cross sections of those transitions have been evaluated.更多还原
