제목 | Preparation and luminescence properties of (Sr/Ca)Si2O2N2:Eu2+ phosphor by spray pyrolysis |
초록 | Phosphor is a key material for lamp and display devices. The technologies on light-emitting diode (LED) have a great attention in order to generate new white-light sources. Eu2+-doped Oxonitridosilicates were reported to have a good emission property under long-wavelength UV light. Conventionally, oxonitrodosilicates are prepared by solid-state methods. In this work, Eu2+-doped (Sr/Ca)Si2O2N2 particles ere prepared by spray pyrolysis and the luminescent characteristics were studied. The prepared MSi2O2N2 particles showed a green emission under long-wave UV and 450 nm blue light. It was found that the emission intensity was greatly enhanced by replacing strontium sites with calcium. |
