摘要
The present invention achieves improvement of the color reproducibility, color rendering properties and light emitting efficiency of a white light emitting diode. The present invention is a red fluorescent material composed of a europium doped lithium lanthanum niobate represented by a general formula of LiLa1-xEuxNb2O7 (0x≦1). The red fluorescent material can efficiently converts light in the light emission wavelength range from 350 to 410 nm of an ultraviolet light emitting diode into red light, and can efficiently converts blue light at 465 nm and green light at 538 nm into red light.
