| titleOfInvention | Composite structure fluorescent ceramic for GaInN white light LED (Light Emitting Diode) and preparation method thereof |
| abstract | The invention provides composite structure fluorescent ceramic for a GaInN white light LED (Light Emitting Diode) and a preparation method thereof. The composite structure fluorescent ceramic is formed by adhering an upper layer of transparent ceramic with a lower layer of transparent ceramic through sides. The chemical composition of the upper layer of transparent ceramic is (CexY1-x)3Al5O12, wherein x is in a value range: 0.0003<=x<=0.06. The chemical composition of the lower layer of transparent ceramic is (CewY1-w)3(CrzAl1-z)5O12, wherein the value ranges of w and z are respectively: 0.0001<=w<=0.06, and 0.0001<=z<=0.06. The composite structure fluorescent material provided by the invention has the advantages of mild color temperature (about 5300K), high color rendering index (Ra>90), excellent temperature quenching property (>400K), simple preparation technology, low cost and the like. |
