Evaluation of luminosity of subpixels on a luminescent monitor based on CdSe/CdS/ZnS quantum dots

Abstract

Modern advances in the synthesis of new materials based on semiconductor CdSe/CdS/ZnS quantum dots have yielded phosphors with a unique set of physical, optical, and surface properties. The high degree of compatibility of quantum dots with some polymers allows one to obtain highly stable polymeric fluorescent layers excited by radiation at a wavelength in the blue region of the visible range. The elaboration of highly efficient and low-cost blue LEDs by Japanese researchers has enabled us to consider the use of these materials for new-generation energy-saving fluorescent screens and video monitors. In this paper we discuss the basic laws of the collimated beam passing through the excitation of the fluorescent material layer and examine the conditions for the highest possible visual brightness of subpixels and the maximum color gamut of the image.
