Abstract:
The present invention provides a zinc oxide-based ultraviolet light emitting material showing intense emission in the ultraviolet region. The present invention is an ultraviolet light emitting material containing: zinc and oxygen as main components; at least one element selected from the group consisting of aluminum, gallium, and indium, as a first sub-component; and phosphorus as a second sub-component. This material has n-type conductivity.
