Study of the Spectral Characteristics of the Photoexcitation of Phosphors Based on Alkali Iodides
A study of the excitation spectra is of very great importance in understanding the nature of various emission bands. When light of a specific spectral composition is absorbed, individual emission bands may be excited; this offers the possibility of separating these out and controlling their behavior in relation to various external factors. By excitation spectrum we mean the relation between the active absorption (active in respect of a given form of luminescence) and the wavelength of the exciting light [77, 78], However, before studying the active part of the absorption, we shall review published data relating to the absorption of alkali halide salts.
