Embodiment Construction
[0028] The present invention provides a new polishing method for a light-emitting element of a light-emitting device. The light-emitting element of the present invention is a light-emitting ceramic or light-emitting glass. After the light-emitting element is subjected to the polishing method of the present invention, a flat surface can be formed, and then A reflective layer or the like can be pasted on the surface to further form a light emitting device. The polishing method of the present invention can effectively solve the problem that the micron-scale undulating concave-convex surface is formed during polishing in the prior art, and the concave-convex surface is covered with a reflective layer, which leads to the problem that the reflective layer is not firmly bonded and easy to fall off.
[0029] The polishing method of the present invention is applied to a light-emitting element formed by sintering at least two raw materials including A-phase raw material and Y-phase raw m...

Abstract
The invention discloses a light emitting element and a high-energy particle radiation method and a polishing method of the light emitting element. According to the polishing method of the light emitting element disclosed by the invention, high-energy ions are adopted for radiation with gradient increase of energy to the light emitting element, so that a phase A of the light emitting element is uniformly damaged within preset depth range below the surface of the light emitting element till the Moh's hardness of the phase A is generally identical to that of a phase Y, and later the light emitting element after radiation is polished to the depth so as to obtain a flat surface. A micron-order concave and convex surface caused by different hardness and grinding velocities of different phases can be avoided, a reflection layer and the like can be solidly adhered to the surface of the light emitting element, and are not easy to drop off.
Description
technical field [0001] The invention belongs to the technical field of light-emitting materials, and in particular relates to a light-emitting element used in a light-emitting device and a high-energy ion radiation method and a polishing method for the light-emitting element. Background technique [0002] Currently there is a light-emitting element obtained by mixing and sintering phosphor powder and glass powder or ceramic powder, such as luminescent ceramics / luminescent glass. The luminescent ceramic / luminescent glass forms a luminescent device by adhering a reflective layer and a heat-conducting supporting device on the side facing away from the excitation light, and is used for converting the excitation light into a subject light of a predetermined wavelength. Since the Mohs hardness of the phase formed by phosphor powder sintering is different from that of glass powder or ceramic powder, the grinding rate is different. Therefore, when polishing the light-emitting elemen...
