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 La and Ti oxide 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 La2 TiO5, LaTi2 O9 and La4 Ti9 O24. 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 temperature range of 1, 000 -1, 50O0C, and thus is simple in preparing process to save cost.
