Abstract
Disclosed is an ultraviolet fluorescent material having high light emission efficiency, wherein the peak wavelength of ultraviolet light to be emitted can be controlled by having a quantum dot structure wherein a fine crystal of zinc oxide having an average diameter of 1-10 nm serves as a core, and the surface of the zinc oxide fine crystal is covered with at least one of LiGaO, LiAlO, NaGaOand NaAlO, which has a crystal structure similar to that of the zinc oxide and low lattice mismatch and hardly suffers from structural defects, or a solid solution thereof.
