We studied the features of the appearance of broadband “white” emission in CaF2-x mol% ErF3 and ZrO2-x mol% Er2O3 (x = 0–25) nanosized dielectric particles upon their excitation by intense laser radiation with λexc = 1550 nm. Comparison of the results of this study with the results obtained previously for other materials doped with Er3+ ions confirmed the thermal nature of the observed emission and made it possible to identify the main factors affecting its occurrence. These include the band gap of the material and the presence of defects in its structure. A method of applying the effect in dermatology is proposed.

掺杂 Er3+ 离子的 CaF2 和 ZrO2 纳米级介电粒子的黑体发射
我们研究了 CaF 2 - x mol% ErF 3和 ZrO 2 - x mol% Er 2 O 3 ( x = 0-25) 纳米介电粒子在强激光辐射激发下出现宽带“白”发射的特征λ exc = 1550 nm 。将本研究的结果与之前获得的其他掺有 Er 3+的材料的结果进行比较离子证实了观察到的发射的热性质，并有可能确定影响其发生的主要因素。这些包括材料的带隙及其结构中是否存在缺陷。提出了一种在皮肤病学中应用该效果的方法。
