摘要

研究了用通量法合成的未掺杂Al(PO3)3晶体在VUV同步加速器激发下的光致发光特性。用FLAPW方法计算了Al(PO3)3晶体的电子结构。Al(PO3)3的PL发射光谱显示出紫色和黄红色光谱区。所得结果表明,磷酸基的电子态在铝(PO3)3晶体的本征发光过程中起积极作用。

VUV spectroscopy and electronic structure of Al(PO3)3 crystals
The photoluminescence properties of undoped Al(PO3)3 crystals synthesized by flux method are studied under VUV synchrotron excitations. The electronic structure of Al(PO3)3 crystals is calculated by the FLAPW method. The PL emission spectra of Al(PO3)3 reveal emission bands in the violet and in the yellow-red spectral regions. Obtained results point to an active role of the electronic states of phosphate groups in the processes of intrinsic luminescence in Al(PO3)3 crystals.
