摘要： A UV emitting device, having
- at least one first phosphor which absorbs UV radiation of a wavelength shorter than 200 nm and emits UV radiation of a wavelength between 220 nm and 245 nm, and
- at least one second phosphor which absorbs UV radiation of a wavelength between 220 nm and 245 nm and emits UV radiation of a wavelength between 250 nm and 315 nm.
