METHOD OF FORMING A RED PHOSPHER AND LIGHT-EMITTING DEVICE HAVING THE RED PHOSPHER |
摘要 |
PURPOSE: A method for forming a red phosphor is provided to ensure relatively inexpensive formation costs since inexpensive tellurium and manganese are used as active ions. CONSTITUTION: A method for forming a red phosphor comprises the steps of: (S10) preparing a mixture of a metal-containing material represented by AB, tellurium(Te)-containing material, and manganese(Mn); and (S20) heat-treating the mixture in an airtight container to form a red phosphor of chemical formula: AB_x:Mn_y,Te_z. The heat-treating step is performed at a temperature of 800~1200°C.
