| titleOfInvention | Pigmented Red Luminescent Phosphor and Manufacturing Method Thereof |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a red light emitting phosphor with pigments and a method for producing the same, wherein the pigment is europium-activated yttrium oxide in a pigmented red light emitting phosphor consisting of a red light emitting phosphor and a pigment blotter adhered to the surface of the phosphor. (Y 2 O 2 S: Eu), a red light-emitting phosphor with a pigment, characterized in that consisting of indium sulfide (In 2 S 3 ) and iron oxide (Fe 2 O 3 ), indium oxide (In 2 S 3 ), yttrium oxide (Y 2 O 3 ) and europium oxide (Eu 2 O 3 ) were mixed and placed in a heat resistant container and calcined for 2 to 8 hours in a hydrogen sulfide (H 2 S) gas atmosphere at a temperature in the range of 700 to 950 ° C. Pulverizing to prepare a mixture of europium-activated yttrium sulfate (Y 2 O 2 S: Eu) and indium sulfide (In 2 S 3 ); and mixing and dispersing the mixture and iron oxide (Fe 2 O 3 ) to mix pigments To prepare a step, using the blended pigment in red It provides a process for the preparation of a pigment adhered red light-emitting phosphor comprising the step of attaching the core body to the light-emitting phosphor. |
