Abstract:
The present disclosure provides a radiation device. The radiation device includes a first light emitting diode (LED) operable to emit light having a first central wavelength; a second LED configured adjacent the first LED and operable to emit light having a second central wavelength substantially less than the first central wavelength; and a luminescent material disposed on the first LED and the second LED. The luminescent material includes a strontium silicon nitride (SrSi6N8) doped by one of cerium (Ce3+) and cerium, lithium (Ce3+, Li+).
Abstract:
The present invention provides a phosphor composition for AC LEDs, which is represented by the following formula (I): M1−x−ySi2O2−wN2+2w/3:Eux,Ry (I) wherein, M, R, x, y, and w are defined the same as the specification. In addition, the present invention also provides an AC LED manufactured with the same.
Abstract:
Disclosed is a phosphor and a method for preparing the same. The phosphor comprises a material having a general composition formula expressed by M1Si6N8−xOx (satisfying 0≦x≦1), where M is alkaline earth metal.
