简介 A vacuum ultraviolet-excited phosphor is composed of a gadolinium-activated rare-earth aluminum-scandium borate that is represented by a general formula (Y 1-x Gd x )Al 3-y Sc y (BO 3 ) 4 (where 0 < x ‰ 1, 0 < y ‰ 3). This vacuum ultraviolet-excited phosphor, when irradiated by vacuum ultraviolet light having a wavelength of 200 nm or less, can produce ultraviolet light having wavelength in the range from 312 nm to 315 nm with higher efficiency and stronger emitted intensity, and can obtain a higher areal intensity ratio than a phosphor of the prior art.
