摘要 |
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+).
