An infrared light-excited light-emitting substance given by the general formula: RlxR2(1-x)BazCl3+2z where R1 is a rare-earth element, x satisfies the relation 0.01 < x </= 1, R2 is another rare-earth element, and z satisfies the relation 1 < z < 4. Preferably, the substance is a transparent crystal having a transparency exceeding 70% in a wavelength range from 400 to 1500 nm, excluding wavelengths absorbed by rare-earth ions. The light-emitting substance can convert infrared light into visible light in a wavelength range from blue light to green light at a high conversion efficiency. |
