| 摘 要： | 制备了一种Ho3+/Tm3+/Yb3+共掺铝硅酸盐微晶玻璃。研究了玻璃基质的吸收光谱和上转换发光光谱,分析了上转换发光机制。发现:在975nmLD激发下,可同时观察到明显的蓝光(476nm)、绿光(544nm)和红光(656nm)上转换发光。同未热处理的玻璃相比,处理后的微晶玻璃的蓝光、绿光和红光的发光强度分别增加了41.1、7.0和0.6倍。比对色坐标发现:微晶玻璃的色坐标CIE-x=0.520,CIE-y=0.360,而未热处理玻璃的色坐标CIE-x=0.284,CIE-y=0.327。上转换发光基质分析表明,上转换蓝光是Tm3+的三光子吸收过程,上转换绿光和红光是Ho3+的双光子吸收过程。这一系列的结果表明,Ho3+/Tm3+/Yb3+共掺铝硅酸盐玻璃可能对三维立体显示的潜在应用有所帮助。

| Abstract: | Ho3+/Tm3+/Yb3+-codoped aluminum silicate glass ceramic was prepared. The ceramic was investigated for its absorption and upconversion spectra, as well as the CIE coordinate. Accordingly, upconversion luminescence mechanisms were analyzed. The blue (476 nm), green (544 nm), and red (656 nm) emission were simultaneously observed at room temperature under 975 nm diode laser excitation. Compared with the glass sample, the blue (476 nm), green (544 nm) and red (656 nm) emission intensity of the glass-ceramic inc... |
