Tungstate / molybdate fluorescent materials for indoor plant lighting and silicon-based solar cell spectral conversion

Abstract

Tungsten / molybdate fluorescent materials, used in indoor plant lighting and spectral conversion in silicon-based solar cells, belong to the technical field of fluorescent materials science. The chemical formula is A9M. 2(1‑x‑y) N4O 24 xBi, yR, A is one or more of Sr, Ca, and Ba; M is one or more of La, Gd, and Y; N is one or a combination of W and Mo; O is oxygen; R is one or a combination of Yb and Nd; 0.01≤x≤0.25; 0.00≤y≤0.11. Used for indoor plant lighting and spectral conversion in silicon-based solar cells. Can provide chlorophyll a, chlorophyll b, carotenoids, and photopigment P. R and P FR It absorbs blue light in the 400-500nm range and red light in the 600-700nm range; it also absorbs ultraviolet and visible light and converts it into near-infrared light, thus improving the utilization rate of sunlight.
