Abstract

Un dispositivo de tubo de rayos catódicos, cuya ventana de vidrio está provista de una capa luminiscente que contiene un sulfuro de cadmio y zinc, que se aplica por medio de un aglutinante orgánico, caracterizado porque al menos los granos del sulfuro de cadmio y zinc se recubren completamente con una capa inorgánica que deja pasar los electrones y la luz luminiscente producida y que no es soluble en agua.
