一、简介:磷光现象发现于17世纪初叶,当时对这种现象未作系统的研究,仅为炼金术士们意图寻找贵金属过程中遇到的一种情况。18世纪是研究晶态燐光体的转折点,开始通过试验,对这一现象进行研究,在18世纪未和19世纪初,俄国科学院院士B.B.彼得罗夫成功地研究了发光现象。在1839～1882年间E贝克勒尔,Bacquercl进行了许多燐光现象的定量研究,他首先作出燐光仪,研究了许多种燐光体的裒落规律和发光光谱对于激发性质的关系。在上世纪的七十年代末和
I. Introduction: Phosphorescence was discovered in the early 17th century when there was no systematic study of this phenomenon, only a case of the alchemists’ attempts to find precious metals. The eighteenth century was a turning point in the study of crystalline phosphors and began to test this phenomenon. In the late eighteenth century and early nineteenth century, B.B. Petrov, a member of the Russian Academy of Sciences, successfully studied the phenomenon of luminescence. During 1839-1882, Bacquercl conducted numerous quantitative studies of catalepsy. He first made a calender to study the law of fall of many kinds of cooters and the relationship between the luminescence spectra and the excitation properties. In the late seventies of the last century
