Abstract
PURPOSE: To provide a fluorescent material having white mateial color, excellent temperature characteristics and spectral reflectance, and improved light-emitting efficiency especially at high temperature, and composed mainly of a red light- emitting fluorescent material consisting of a rare earth metal salt of an acid composed mainly of vanadic acid doped with europium and represented by a specific formula.
CONSTITUTION: The objective fluorescent material is composed of a red light- emitting fluorescent material consisting of a rare earth metal salt of an acid composed mainly of vanadic acid doped with Eu and represented by the formula [Ln is Y, Gd or La;0<x≤0.01(preferably 0.001≤x≤0.00005); 0.005≤y≤0.2(preferferably0.015≤y≤0.070); 3.0≤z≤4.0]. The above fluorescent material can be prepared by weighing definite amounts of the oxides of the constituent elements or raw material salts which can be oxidized easily by heating, mixing the components by a ball mill, etc., and calcining at 800W1350°C for 0.5W4.0 hours.
