The light emitting device includes a light emitting diode and luminescent substances disposed around the light emitting diode, to absorb at least a portion of light emitted from the light emitting diode and emitting light having different wavelength from that of the absorbed light. The luminescent substances have Eu2+-doped silicate luminophores in which solid solutions in the form of mixed phases between alkaline earth metal oxyorthosilicates and rare earth metal oxyorthosilicates are used as base lattices for the Eu2+activation leading to luminescence. The luminescent substances are used as radiation converters to convert a higher-energy primary radiation, for example, ultra violet (UV) radiation or blue light, into a longer-wave visible radiation and are therefore preferably employed in corresponding light-emitting devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting device employing luminescent substances with oxyorthosilicate luminophores","description":"A light emitting device having oxyorthosilicate luminophores is disclosed.
