Title (EN) NITRIDE FLUORESCENT SUBSTANCE AND LIGHT EMITTING DEVICE COMPRISING SAME
(FR) SUBSTANCE FLUORESCENTE AU NITRURE ET DISPOSITIF ÉLECTROLUMINESCENT COMPRENANT LADITE SUBSTANCE FLUORESCENTE
(ZH) 一种氮化物荧光物质及含有该荧光物质的发光装置
Abstract:
(EN) A nitride fluorescent substance and a light emitting device comprising the fluorescent substance, relating to the technical field of inorganic luminescent materials. The nitride fluorescent substance contains: compounds having an aR, bEu and cCe structure, for example, MmAl xSi yN3. The fluorescent substance has high physical and chemical stability and good crystallization, and thus has higher external quantum efficiency. When the fluorescent substance is used in the light emitting device, the advantages of good stability and high external quantum efficiency can be fully exerted, and thereby the light emitting efficiency and stability of the light emitting device are further improved.
(FR) L'invention se rapporte au domaine technique des matériaux luminescents inorganiques, et concerne une substance fluorescente au nitrure et un dispositif électroluminescent comprenant ladite substance fluorescente. La substance fluorescente au nitrure contient des composés ayant une structure aR, bEu et cCe, par exemple, MmAl xSi yN3, et présente une stabilité physique et chimique élevée ainsi qu'une bonne cristallisation, disposant ainsi d'un rendement quantique externe supérieur. Quand la substance fluorescente est utilisée dans le dispositif électroluminescent, les avantages d'une bonne stabilité et d'un haut rendement quantique externe peuvent être pleinement exercés, améliorant ainsi davantage l'efficacité d'électroluminescence et la stabilité du dispositif électroluminescent.
(ZH) 一种氮化物荧光物质及含有该荧光物质的发光装置,属于无机发光材料技术领域。所述氮化物荧光物质含有如MmAl xSi yN3:aR,bEu,cCe结构的化合物,该荧光物质具有很高的物理稳定性和化学稳定性,同时该荧光物质结晶较好,因此,具有较高的外量子效率。该荧光物质应用至发光装置中时,能够充分发挥稳定性好、外量子效率高的优势,进而提高发光装置的发光效率和稳定性。
