Abstract

A new universal law of photoluminescence is established, according to which the ratio of the luminescence spectrum when excited at a given wavelength of light to the excitation spectrum of luminescence when observed at the same wavelength is a universal function determined by the emission spectrum of a blackbody. This relationship is based on the principle of detailed equilibrium for photoluminescence, which is ultimately a generalization of Kirchhoff’s fundamental law in relation to any material bodies, including phosphors.

光致发光的新通用定律

摘要

建立了新的光致发光通用定律，根据该定律，在给定波长的光下激发的发光光谱与在相同波长下观察到的发光的激发光谱的比率是由黑体的发射光谱确定的通用函数。该关系基于光致发光的详细平衡原理，该原理最终是基尔霍夫关于包括磷光体在内的任何物质的基本定律的推广。
