Title:
WAVELENGTH CONVERSION MEMBER, BACKLIGHT UNIT, IMAGE DISPLAY DEVICE, PRODUCTION METHOD FOR WAVELENGTH CONVERSION MEMBER, AND INORGANIC PHOSPHOR PROCESSING LIQUID
Document Type and Number:
WIPO Patent Application WO/2022/014653
Kind Code:
A1
Abstract:
This wavelength conversion member contains inorganic phosphors and a resin cured product containing the organic phosphors. When peak wavelengths of fluorescence spectrums are measured by time-resolved fluorescence spectroscopy for the wavelength conversion member, the absolute value (| λ0–λτ |) of the difference between the peak wavelength λ0 of a fluorescence spectrum of an initial period for at least one type of the organic phosphor and the peak wavelength λτ of a fluorescence spectrum observed after only a fluorescence life τ has elapsed from the observed time point of the fluorescence spectrum of the initial period is 6 nm or less.
