在本研究中，在透明的Ho3+和Tm3+共掺杂的锆钛酸铅(PLZT)陶瓷中，观察到了位于553 nm和696 nm的明显的上转换发射峰。研究了在约2μm处随温度变化的可见光上转换发射和中红外光致发光，观察到了从黄绿色到红色的明显的发光颜色调制。通过分析发射峰的抑制和增强，研究了Ho3+和Tm3+离子之间的能量传递。在1.95μm处获得了随机的激光发射峰，半高宽为5 nm，这是发展陶瓷材料中红外激光器的理想选择。
In this study, obvious up-conversion emission peaks centred at 553 nm and 696 nm were investigated in transparent Ho3+and Tm3+co-doped lead lanthanum zirconate titanate (PLZT) ceramics. Temperature dependent visible up-conversion emission and mid-infrared photoluminescence at approximately 2.0 μm were studied, and obvious luminous color modulation from yellow-green to red was observed. Energy transfer between Ho3+and Tm3+ions was studied by analyzing the suppression and enhancement of the emission peaks. Moreover, random lasing emission peaks at 1.95 μm were achieved with a full width at half maximum of 5 nm, which was desirable for developing mid-infrared lasers in ceramics materials.
