Abstract
Disclosed is low-voltage phosphor material having a high level of brightness and a manufacturing method thereof. The phosphor material includes (ZnCd)S or ZnS based compound phosphor material, and a metal added to the phosphor material, the metal having properties for preventing oxidation and reducing surface charge of the phosphor material. The method of manufacturing the phosphor material includes the steps of adding (ZnCd)S based compound phosphor material or ZnS based compound phosphor material to a vehicle and mixing the resulting mixture, and adding a metal to the mixture, the metal having properties for preventing oxidation and reducing surface charge of the phosphor material. Preferably, the metal is Zn having a diameter of 0.1 to 10 .mu.m and a purity of 95%. Also preferably, the metal is 0.01 to 10.0 wt % based on the wt % of the phosphor material.
