A kind of fluorescent
powder is based on
metal sulfoxide, Eu2+ and Cu2+ are co-activators, and other ions are sensitizers. aA, bB, cC, dD, eE. Among them: A is one or two of Y3+, La3+, Ce3+, Pr3+, Nd3+, Sm3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, Tm3+, Yb3+, Lu3+; B is Bi3+, Sb3+, Mn2+, Pb2+ One or two; C is one or two of F-, Cl-, Br-, I-; D is one or two of Se2-, Te2-. E is one or more of Li+, Na+, K+, Rb+, Cs+, Ag+ and H3BO3. The
phosphor has a
broadband dual excitation spectrum and a
broadband dual emission spectrum, the dual excitation
band spectrum is located in the 200-425nm and 425-610nm area, and the
dual emission band spectrum is located in the 400-550nm and 600-750nm area. Phosphors can be used in agricultural films, solar photovoltaic cells and LED devices.
