PURPOSE : A red phosphor for use in solid state lighting is provided to enable efficient excitation by near UV light, blue light and green light and to allow preparation by employing a solid state sintering method at an ambient air at atmospheric pressure and temperature range of 1, 000 -1, 500 deg.C.CONSTITUTION : A red phosphor for use in solid state lighting includes La and Ti oxides as a main composition and a rare earth element as a subsidiary composition. 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, and Ho. The La and Ti oxide may be one selected from a group consisting of La2TiO5, LaTi2O9 and La4Ti9O24.COPYRIGHT KIPO 2011 |
