Abstract
Phosphors having high luminescence characteristics are provided while achieving manufacturing cost reductions by minimizing the usage amount of Eu, the luminescence center. Also provided are a display device (PDP, etc) and a fluorescent lamp having excellent display and/or luminescence characteristics as a result of using the phosphors, while achieving manufacturing cost reductions by minimizing the Eu usage amount.
