Title:
WAVELENGTH CONVERSION FILM, WAVELENGTH CONVERSION PARTICLES, DISPERSION LIQUID, AND METHOD FOR PRODUCING WAVELENGTH CONVERSION PARTICLES
Document Type and Number:
WIPO Patent Application WO/2019/138958
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a wavelength conversion film which has transmittance and haze characteristics, and which exhibits excellent workability and durability when applied to a film for agricultural use, while having high yield increase effect for crops; wavelength conversion particles which are applied to this wavelength conversion film and have excellent wavelength conversion characteristics; a dispersion liquid which contains the wavelength conversion particles; and a method for producing the wavelength conversion particles. A wavelength conversion film according to the present invention is characterized by containing at least wavelength conversion particles, and is also characterized in that: the wavelength conversion particles are inorganic particles; the inorganic particles absorb at least light having a wavelength of less than 600 nm and emit light having a wavelength within the range of 600-750 nm; and the inorganic particles have an average particle diameter within the range of from 10 nm to 10 μm.
