摘要：

We employed an oxygen-pressure method as a novel approach to improve the emission intensity of a Ca14Zn6Al10O35:Mn4+ phosphor. With this new approach, the Ca14Zn6Al10O35:Mn4+ phosphor exhibited near-infrared emission under excitation at 450 rim, and the emission intensity of a Caw Zn-6(Al0.97Mn0.03)(10)O-35 phosphor was effectively enhanced by approximately 143% compared with that of a Ca14Zn6(Al0.97Mn0.03)(10)O-35 phosphor synthesized by a conventional solid-state reaction method in air.
