| 简介 |
The present invention provides an oxide-based fluorescent material which uses an element other than a rare earth element as a light-emitting element, uses inexpensive raw materials, and exhibits high luminous efficiency. More specifically, the present invention provides a fluorescent material characterized by being represented by the formula H1-xZr2P3O12-(x/2) (1) [in the formula, x is at least 0.005 but lower than 0.4], and a fluorescent material characterized by being represented by the formula (Mn+ yH1-ny)1-xZr2P3O12-(x/2) (2) [in the formula, M denotes a metallic element and n denotes the average valency of the metallic element M. In addition, x is at least 0.005 but lower than 0.4, and y is at least 0.01 but lower than 0.90/n]. |
