Abstract
The invention provides quickly-attenuated and ultraviolet-excited terbium-ion-doped luminescent glass. The glass is prepared by being melted at certain temperature T1 and annealed at temperature T2. The luminescent center of the luminescent glass is Tb3+, and Cu+ serves as coactivator and sensitizer. The excitation wavelength of the luminescent glass covers UVA, UVB and UVC ultraviolet regions, the luminescent glass emits composite high-intensity green fluorescent light with efficient main emission peaks being about 485 nm and about 541 nm, and decay time is in a microsecond level. The luminescent glass expands an excitation region to a deep-ultraviolet region of 260 nm, and an excitation band covers 260 nm-380 nm. The luminescent glass is a novel luminescent material capable of meeting requirements for near-ultraviolet and deep-ultraviolet wavelength excitation sources and short response time.
