一般說明
La2O3是一种宽带隙p型半导体，也称为倍半氧化镧。它是唯一具有空Ln-4f外壳的镧系氧化物，广泛用于制备光学材料、电介质和导电陶瓷。La2O3也可用作许多有机转化的催化剂。
應用
氧化镧（III）提高了玻璃的耐碱性能，由于高折射率和低色散，被广泛应用于照相机和望远镜透镜、红外吸收玻璃和其他特种光纤的制备。例如，可作为起始材料制备用于诊断X射线屏蔽的La2O3-CaO-B2O3-SiO2玻璃。
可用于制备热膨胀系数高、导热系数低的热障涂料。
还可用作合成二苯基硫化物和硒化物的可循环催化体系。

Low-power-threshold cw laser-induced incandescence (CWLII) has been observed in La(2)O(3):Er(3+)-Yb(3+) phosphor on excitation by a 976 nm IR laser. It is suggested that incandescence originates from the extensive heating induced by the nonradiative processes taking place following the laser excitation.
