COLUMNAR STRUCTURE, METHOD FOR THE PRODUCTION THEREOF AND DEVICES BASED THEREON

摘要

The invention relates to lighting engineering, microelectronic components and to electronic and electromagnetic material science. Said invention makes it possible to increase phosphor conversion efficiency, reduce the cost of the structure production and to improve consumer properties of devices based thereon. The inventive method consists in using columnar structures made of suitable materials, wherein spaces between such structures remain transparent for luminescence exciting particles and the light-guiding properties of the columnar structures ate preserved. The resuh is attained by involving the part of the side surfaces of the columnar structures in particle absorption. A method for producing columnar structures and the production of cathodoluminescent screens, light sources. X-ray image converters and optical dosimeters based on said structures are also disclosed.
