Single crystalline thin film screens for cathode ray tubes: possibilities of application, peculiarities, and light parameters

In present work the peculiarities of preparing of single crystalline thin films (SCFs) Y3Al5O12 by liquid phase epitaxy technique and its light emission characteristics in different spectral regions are investigated. These films are luminescent screens for cathode ray tubes with high resolution prepared on base of Y3Al5O12 doped by rare-earth and isoelectronic impurities. The advantages of these screens over bulk crystalline and powder analogs have been shown. The possibilities of cathode ray tube application with SCF screen in raster optical microscopes, proectional systems and original devices for processing of color images from PC display (computer slider) are discussed.
