Abstract
A method for producing sheets of glass phosphor, including following steps of: taking glass powder, phosphor powder and a bonding agent to mix to form a mixture, wherein the glass powder and the phosphor powder are mixed first, and then the glass powder and the phosphor powder are mixed with the bonding agent; compressing the mixture to form a tablet; sintering the tablet to form a glass phosphor body; cutting the glass phosphor body to form at least one sheet body.

A method for producing sheets of glass phosphor, including following steps of
- taking glass powder, phosphor powder and a bonding agent to mix to form a mixture, wherein the glass powder and the phosphor powder are mixed first, and then the glass powder and the phosphor powder are mixed with the bonding agent;
- compressing the mixture to form a tablet;
- sintering the tablet to form a glass phosphor body;
- cutting the glass phosphor body to form at least one sheet body;
- wherein the bonding agent takes up 30% to 50% of a total volume of the mixture, and the bonding agent is viscous so that the mixture is flowable;
- wherein after the glass phosphor body is sintered, the glass phosphor body goes through an annealing processing step, and a temperature of the annealing processing step is between 300° C. to 500° C.;
- wherein the glass phosphor body has a forming density, and the forming density is between 0.001 g/mm3 to 0.004 g/mm3 .
