| 简介 | A rare earth element phosphovanadate-based red phosphor, and a cold cathode fluorescent lamp using the phosphor are provided to improve luminous characteristic and color purity at the excitation wavelength of 254 nm. A rare earth element phosphovanadate-based red phosphor excites in the long wavelength UV range of 250 ~ 350 nm and is represented by (Y_(1-a-b-d) Gd_b Sc_d)(P_(1-c) V_c)O4 : Eu_a, wherein 0.1 <= a <= 0.4; 0 <= b <= 0.6; 0.4 <= c <= 1; and 0 <= d <= 0.4. | ||
