Abstract

The red light-emitting fluorescent material of this invention can emitting red fluorescence by excitation light of wavelength in 370 to 410 nm and 455 to 470 nm efficiently, and suit for white light-emitting device which has violet light-emitting diode with light-emitting peak in 370 to 410 nm or blue light-emitting diode with light-emitting peak in 455 to 4770 nm as light-emitting device. Also the red light-emitting fluorescent material of this invention may emits red fluorescence by excitation light of wavelength in 520 to 550, therefore the collocation of light-emitting device or fluorescent material can be extended in the white light-emitting device and the light can be emitted in high luminance. The red light-emitting fluorescent material of this invention can emits red fluorescence by excitation light and shows as formula Sr(La1-xEux)6W10O40(0 < x ≤ 1).
