一、导言燐光体,是指在紫外辐照、X射线、电子轰击、摩擦或其他一些激发方式作用下可以产生辐射的一类材料。这种发射称为发光(Luminescence)。例如,管状荧光灯中,253.7nm汞线能量被转换成复盖整个可见区域的辐射;在电视显像管中高速电子的能量被转换成可见辐射。有关发光方面的一般导论,可参阅下列文献:Curie(1963)、Garlick(1958)、Goldberg(1966)和Riechl(1971)。本文是一篇有关基础研究方面的评述。所涉及 I. INTRODUCTION Ciliary body is a kind of material that can produce radiation under ultraviolet radiation, X-ray, electron bombardment, friction or some other excitation mode. This type of launch is called luminescence. For example, in a tube-shaped fluorescent lamp, 253.7 nm of mercury is converted into radiation that covers the entire visible region; the energy of high-speed electrons in a television picture tube is converted into visible radiation. For a general introduction to luminescence, see the following: Curie (1963), Garlick (1958), Goldberg (1966) and Riechl (1971). This article is a commentary on basic research. Involved
