我们报告了在 800 nm 二极管激光激发下获得的钕激活氟铝酸盐玻璃的上转换发光。观察到几种反斯托克斯发射：在 588、607、720 和 750 nm 处，并指定适当的跃迁。对于后两种发射，我们观察到对温度的强烈依赖性：720 nm 发射强度随温度降低，而 750 nm 发射强度随温度增加。根据受氧影响的位点对无辐射跃迁和多声子反斯托克斯激发的影响提出了解释。该模型为实验数据提供了合理的拟合。 (c) 2005 Elsevier B.V. 保留所有权利。
We report on the upconverted luminescence in neodymium-activated fluoroaluminate glass obtained with 800 nm diode laser excitation. Several anti-Stokes emissions: at 588, 607, 720 and 750 nm are observed and appropriate transitions are assigned. For both latter emissions we observe strong dependence on temperature: the 720 nm emission intensity decreases with temperature, whereas the 750 nm emission increases. Interpretations are presented in terms of the influence of oxygen-affected sites on the radiationless transitions and multiphonon anti-Stokes excitation. The models provide reasonable fits to the experimental data. (c) 2005 Elsevier B.V. All rights reserved.
