Abstract
A phosphor including a matrix in the form of titanate expressed by Ca1-xSrxTiO3 (0<x≦0.5), and Pr (praseodymium) and Li (lithium) that are added to the matrix. The phosphor may further include Zn (zinc) that is added as well as the Pr and Li to the matrix. Also disposed is a process of manufacturing the phosphor, including: a mixing step of mixing a matrix material, a first additive material including Pr, and a second additive material including Li, so as to obtain a mixture; and a firing step of firing the obtained mixture at a firing temperature of from 1050 to 1250° C.
