Nitrogen oxide blue-green powder for white light LED
1 Scope
This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of nitrogen oxide blue-green powder for white light LEDs:
Save and accompanying files:
This document applies to nitrogen oxide blue-green powder prepared by liquid phase methods such as high-temperature solid-phase reaction method, co-precipitation method or combustion method: The phosphor is used in
When excited by a light source with a wavelength of 350nm~480nm, it emits blue-green light of 485nm~505nm: This light is different from the light emitted by the excitation source:
The colored light forms white light, which is mainly used to prepare white LED light-emitting devices excited by purple/near-ultraviolet LED chips:
