摘　　要：采用重力沉积技术制备了Ca S:Eu2+,Sm3+红外上转换荧光屏,确定了最佳制屏工艺参数,研究了红外转换荧光屏的性能。设计和制作了耦合短波红外CCD相机,对相机的成像性能进行了试验,结果表明研制的短波红外CCD相机能够实现对1 064 nm、1 550 nm等短波红外激光的探测和成像。采用红外转换荧光屏制作红外CCD相机为短波红外探测器的研制提供了简便、有效的途径。Ca S：Eu^2＋,Sm^3＋infrared up-conversion screens were prepared by the gravity deposition method,the optimum preparation parameters of screens were determined and the properties of the infrared up-conversion screens were researched.A coupled short wavelength infrared CCD camera was designed and manufactured.The imaging properties were tested and the results show that the obtained coupled CCD camera is able to detect 1 064 nm and 1 550 nm.It would provide an efficient alternative technology for the short wavelength infrared detector through coupling the up-conversion fluorescence screens to the CCD cameras.
