Document Type and Number:
WIPO Patent Application WO/2022/163269
Kind Code:
A1
Abstract:
In this fluorescent material, which contains Cr3+ and emits near infrared light, the fluorescent material matrix crystals have the same crystal structure as the compound Mg3Ga2GeO8, the fluorescent spectrum FF1 has a fluorescence peak FPF1 in the wavelength range greater than or equal to 700 nm and less than 900 nm, and the fluorescent spectrum data group FD, which is an aggregation of spectral intensities of the fluorescent spectrum FF1 every 10 nm, exhibit a single peak in the wavelength range greater than or equal to 700 nm and less than 900 nm.
