| 简介 |
There are described a red phosphor for use in solid state lighting and a method for preparing the same, which can be excited efficiently with near UV light, blue light and green light. The red phosphor for use in solid state lighting includes a Zn and Ti oxide as a main element and a rare earth element as an additive element. The rare earth element includes a single element or one or more combination thereof selected from a group consisting of Eu, Er, Dy, Sm, Tb, Ce, Gd, Nd, Dy, Ho and the mixture thereof. The Zn and Ti oxide may be one selected from a group consisting of TiZn2O4. The red phosphor of the present invention can be prepared by employing a solid state sintering method at an ambient air at atmospheric pressure and in a range of 1, 000~1, 500 C° and thus is simple in preparing process to save cost. |
