Abstract: There is herein described a method for forming a ceramic wavelength converter assembly which achieves a direct bonding of an alumina-based ceramic wavelength converter to an alumina-based ceramic substrate such as polycrystalline or sapphire. The method comprises applying a silica-containing layer between the converter and the substrate and then applying heat to bond the converter to the substrate to form the ceramic wavelength converter assembly. Because direct bonding is achieved, the ceramic wavelength converter may operate at much higher incident light powers than conventional silicone glue-bonded converters.
Abstract translation: 这里描述了一种用于形成陶瓷波长转换器组件的方法，其实现了氧化铝基陶瓷波长转换器直接结合到诸如多晶或蓝宝石的氧化铝基陶瓷衬底上。 该方法包括在转换器和衬底之间涂覆二氧化硅层，然后施加热量以将转换器结合到衬底以形成陶瓷波长转换器组件。 由于实现了直接接合，所以陶瓷波长转换器可以比传统的硅胶粘合转换器高得多的入射光功率工作。

Abstract: An alumina-based ceramic wavelength converter is described having a surface layer containing a second phase of alumina, preferably as alumina crystallites. The surface layer is formed as a result of the sintering process used to form the bulk ceramic which is itself substantially transparent. The ceramic wavelength converter is combined with a light emitting diode to form a light emitting device. Preferably, the ceramic wavelength converter is comprised of an alumina-based phosphor represented by a general formula A 3 B 5 O 12 :Ce, wherein A is Y, Sc, La, Gd, Lu, or Tb and B is A1, Ga or Sc.
