引言 荧光屏是真空成象器件的重要组成部分之一,荧光屏的质量好坏,直接关系到整个器件的性能,而影响荧光屏好坏的关键问题,除了制屏工艺外就是荧光粉的质量如何。因此,真空成象器件的质量与荧光粉的性能有着密切联系。 荧光粉的颗粒尺寸和尺寸分布是荧光粉能否用于涂屏的主要参数之一,因为它是改变荧光屏性能的重要因素,粒度小可使屏上的粉层厚度变薄,光散射小,能提高荧光屏的分辩率,改善象质。
Introduction Fluorescent screen is an important part of the vacuum imaging device, the quality of the screen is directly related to the performance of the entire device, and the key issues affecting the screen is good, in addition to screen-making process is the quality of the phosphor. Therefore, the quality of vacuum imaging devices and phosphor properties are closely linked. Phosphor particle size and size distribution of the phosphor can be used for coating the screen one of the main parameters, because it is an important factor to change the performance of the screen, the particle size can be small on the screen of the powder layer thickness thin, light scattering, Can improve the screen resolution, improve image quality.
