摘要： A phosphor converted light emitting device includes a semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region, the light emitting layer being configured to emit light having a first peak wavelength; a first phosphor configured to emit light having a second peak wavelength; and a second phosphor configured to emit light having a third peak wavelength. The second phosphor is an Eu 3+- activated phosphor, configured such that in the excitation spectrum at 298K and 1.013 bar, a maximum intensity in a wavelength range between 460 nm and 470 nm is at least 5% of a maximum intensity in a wavelength range between 220 nm to 320 nm.

摘要： Light emitting device comprising an excitation energy source to deliver a primary excitation energy and a converting element essentially comprising Eu3+- phosphor material to at least partly convert the primary energy into a secondary radiation whereby in the excitation spectrum of the Eu-comprising phosphor material at 298 K and 1,013 bar the maximum intensity in the wavelength range between ≥ 460 nm to ≤ 470 nm is ≥5% of the maximum intensity in the wavelength range between ≥ 220 nm to ≤ 320 nm. The excitation energy source can be any suitable energy source to excite a secondary light emission such as electron beam sources (e.g. electron guns in CRTs) or light sources such as organic LEDs, inorganic LEDs or laser diodes.
