一 前言 锑、锰激活的卤磷酸钙荧光粉(以下简称卤粉)自1942年由麦基格发明作为荧光灯用荧光粉以来,一直沿用迄今,三十多年来人们对卤粉的发光机理进行了深入研究,并就其制备工艺、成分配比、颗粒控制、后处理等有关问题进行了大量研制、试验工作,使荧光灯光效由四十年代的40余流明/瓦提高到现在的75—85流明/瓦(冷白色、白色、暖白色荧光灯)、60—67.5流明/瓦(日光色荧光灯)。我国荧光灯光效还比较低,据1979年全国荧光灯质量 An Introduction Antimony and manganese activated calcium halophosphate phosphor (hereinafter referred to as halogen powder) was invented by McKig in 1942 as a phosphor for fluorescent lamps and has been used so far for more than thirty years, the luminescent mechanism of halogen powder In-depth study, and its preparation technology, composition ratio, particle control, post-processing and other related issues carried out a large number of research and experimental work so that the fluorescent efficiency of light from the forties 40 lumens / watt increased to the present 75- 85 lm / W (cool white, white, warm white fluorescent), 60-67.5 lm / W (daylight fluorescent). China’s fluorescent efficiency is still relatively low, according to the quality of the national fluorescent lamp in 1979
