摘要 获得了BaTiO3晶体（通过不同方法和不同铁掺杂量获得）在宽温度范围内在X射线和紫外（UV）激发下的发光发射。已经获得了各个谱带的半宽度、最大值位置和发射强度的温度依赖性及其对晶体纯度的依赖性。更强烈的发射是以 500 nm (E=0.485 eV) 为中心的复杂带，由 460、500 和 520 nm 的发射带组成。在紫外激发下，仅获得 500 nm 处的复合谱带。
Abstract The luminescence emission under X-ray and ultraviolet (UV) excitation of BaTiO3 crystals (obtained by different methods and with various amount of iron doping) has been obtained in a wide temperature range. The temperature dependence of the half-width, position of the maximum and emission intensity of the various bands has been obtained as well as its dependence on crystal purity. The more intense emission is a complex band centered at 500 nm (E=0.485 eV) composed by emission bands at 460, 500 and 520 nm. Under UV excitation only the complex band at 500 nm has been obtained.
