Light-emitting material

Abstract

Abstract PURPOSE: To provide a red light-emitting material which can be excited by low- energy electron beam, and is composed of a Cr-doped fluorescent material and a low-resistance material composed mainly of zinc oxide. CONSTITUTION: A composition composed of (A) 1 part by weight of a Cr-doped fluorescent material obtained by adding 10 -5 W5×10 -2 g (reduced to Cr 2 O 3 ) of Cr to 1g of an oxide of formula M 2 O 3 (M is B, Al, Ga, or In), and calcining the mixture at 130W1600°C, and (B) 14:1W1:14 parts of a low-resistance material obtained by adding one or more elements selected from B, Al, Ga, In, and Tl, to ZnO.
