Title (EN) OXYNITRIDE PHOSPHOR, PREPARING METHOD THEREFOR, AND WHITE LIGHT EMITTING ELEMENT
(FR) LUMINOPHORE À L'OXYNITRURE, SON PROCÉDÉ DE PRÉPARATION, ET ÉLÉMENT ÉLECTROLUMINESCENT ÉMETTANT DE LA LUMIÈRE BLANCHE
(KO) 산질화물 형광체와 그 제조방법 및 백색 발광소자
Abstract: front page image
(EN)The present invention relates to an oxynitride phosphor, a preparing method therefor, and a white light emitting element, and more specifically, to an oxynitride phosphor characterized by the emission at an emission wavelength of even 500-550 nm using a UV LED and a blue LED as light sources and having a narrow full width at half maximum of 48-80 nm, wherein the oxynitride phosphor has an excellent absorption range of 380-480 nm and facilitates the wavelength shift to even 500-550 nm, to a preparing method therefor, and to a white light emitting element containing the phosphor.
(FR)La présente invention concerne un luminophore à l'oxynitrure, son procédé de préparation, et un élément électroluminescent émettant de la lumière blanche, et plus particulièrement, un luminophore à l'oxynitrure caractérisé par une émission à une longueur d'onde d'émission même de 500 à 550 nm à l'aide d'une DEL UV et d'une DEL bleue utilisées comme sources de lumière et présentant une largeur totale étroite à mi-hauteur de 48 à 80 nm, ledit luminophore à l'oxynitrure présentant une excellente plage d'absorption de 380 à 480 nm et facilitant le décalage de la longueur d'onde jusqu'à même 500 à 550 nm, son procédé de préparation, et un élément électroluminescent émettant de la lumière blanche contenant ledit luminophore.
(KO)본 발명은 산질화물 형광체와 그 제조방법 및 백색 발광소자에 관한 것으로서, 더욱 상세하게는 UV LED 및 청색 LED를 광원으로 하여 발광 파장이 500 ~ 550 nm까지 발광하며, 그 반치폭이 48 ~ 80 nm 정도 좁은 산질화물 형광체를 특징으로 하며, 우수한 380 ~ 480 nm의 흡수 영역을 가지고 500 ~ 550 nm까지 파장이동이 용이한 산질화물 형광체와 그 제조방법 및 그 형광체를 포함하는 백색 발광소자에 관한 것이다.
