MAGNETIC PHOSPHOR COMPLEX AND MANUFACTURING METHOD FOR THE SAME

摘要

PURPOSE: A method for manufacturing a magnetic phosphor complex is provided to ensure magnetism and radiation in a single substance and to prepare a fluorescence composite with new magnetic properties. CONSTITUTION: A method for manufacturing a magnetic phosphor complex comprises the steps of: dispersing a fluorescent substance precursor and magnetic material precursor in ethanol or acetone and mixing the dispersed material using ethylene glycol at 30~70 °C for 1~5 hours; drying the mixture in a powdered state at 100~150 °C; and heat-treating the dried mixture in a mixed gas atmosphere where nitrogen and hydrogen are mixed in a volume ratio of 75~95 : 25~5 at 800~1700 °C.
