Abrégé
(EN)
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.

L'invention a trait à un phosphore de thiogallate représenté par la formule AB2S4. Le phosphore de thiogallate selon l'invention est formé par le remplacement d'une position A nécessitant un ion divalent par un élément trivalent doté d'une taille d'ion similaire à celle de l'élément à la position A et par un élément monovalent doté d'une taille d'ion similaire à celle de l'élément à la position A. Les éléments trivalents et monovalents sont de préférence introduits en quantité égale. En outre, l'invention concerne une diode électroluminescente blanche et permet de fabriquer une diode électroluminescente blanche présentant un excellent rendement lumineux.
