Abstract:
The invention provides a new ultraviolet light-emitting material and ultraviolet light source in which bacteriocidal performance, operating life, and luminescence efficiency are enhanced without any risk of adversely affecting human bodies. An ultraviolet light-emitting material has a composition as represented by Formula (A): (Al1-xScx)2O3 (A) where a dopant, Sc is added to a matrix, Al2O3, and x satisfies 0
