FLUORESCENT MATERIAL FOR WHITE LIGHT EMITTING DIODE AND PREPARATION METHOD THEREOF

摘要

A fluorescent material of a garnet structure comprising an aluminate-based fluorescent material, cerium as an activator and thulium as a coactivator can emit green light with high luminance under an excitation condition by a blue light source, and therefore, it is useful as a fluorescent material for a white light emitting diode.
