LUMINESCENCE, INFRARED RESPONSE AND ENERGY STORAGE OF VARIOUS LUMINESCENT MATERIALS IN RELATION TO PREPARATIVE METHODS AND CONDITIONS.
Abstract
The investigation of the physical properties of phosphors, particularly with respect to infrared response and the relationship to their chemical composition and the conditions under which they are synthesized, was continued. ZnCdS phosphors, with various activators (Ag, Cu, Au, Cr) and coactivators (Al, Cl), were synthesized and single CdS crystals were grown. The following properties of the phosphors were investigated: Fluorescence efficiency, photoconductivity, paramagnetic resonance, its rise and decay, energy storage, thermoluminescence, thermoconductivity, influence of infrared light of various wavelengths on luminescence, photoconductivity and paramagnetic resonance, electro-luminescence and photovoltaic response. General features of the synthesis of these phosphors are described and a general summary of their physical properties is given. The dependence of luminescence and thermoluminescence on infrared irradiation is treated in detail for Cr-activated phosphors. The influence of infrared on various other phosphors is also presented.
