CaS:Cu~+,Eu~(2+)荧光粉添加到高分子溶液中配成转光液,喷涂后自然条件下干燥成膜,测试了薄膜的荧光光谱、透光率、荧光抗衰减性能。结果表明,转光液所成薄膜荧光光谱与其添加的荧光粉光谱一致.具有吸收紫外光发射432nm蓝光和648nm红光,吸收绿光发射648nm红光的作用,转光行为有利于植物光合作用。薄膜可见光区透光率在75%以上,荧光抗衰减性能好。 CaS: Cu ~ +, Eu ~ (2+) phosphors were added to the polymer solution to form a translucent liquid. After spraying, the films were dried under natural conditions to form a film. The fluorescence spectra, transmittance, fluorescence antifade properties . The results showed that the fluorescence spectrum of the thin film grown by the light conversion fluid was the same as that of the phosphor powder added, and had the function of absorbing 432nm blue light and 648nm red light and absorbing green light emitting 648nm red light. Film visible light transmittance of 75% or more, good fluorescence anti-attenuation performance.
