FLUORESCENT MATERIAL AND LIGHT EMITTING DIODE USING THE SAME |
摘要 |
The present invention relates to a thiogallate phosphor expressed as AB2S4. The thiogallate phosphor of the present invention is configured by replacing a position A where a divalent ion is required with a trivalent element having an ion size similar to that of the element at the position A and with a monovalent element having an ion size similar to that of the element at the position A. Preferably, the trivalent and monovalent elements are replaced by the same amount. Further, the present invention relates to a white light emitting diode and is to manufacture a white light emitting diode with excellent luminous efficiency. |
