发光器具和图像显示装置
摘要：
本发明提供了利用AlON荧光体且具有宽色域的发光器具和图像显示装置。本发明的发光器具至少包括发射光源和荧光体或分散有荧光体的透光体，所述发射光源发出波长为410nm以上470nm以下的光。其中所述荧光体包含无机化合物，所述无机化合物包括AlON晶体、AlON固溶体晶体或者具有与所述AlON晶体相同的晶体结构的无机晶体，其中至少包含Mn、必要时的A元素(A元素为一价金属元素)、必要时的D元素(D元素为二价金属元素)、必要时的E元素(E元素为一价阴离子)和必要时的G元素(G元素为不同于Mn、A、Al、O、N、D和E的一种或2种以上的元素)，并且在激发源的照射下发出具有从515nm到541nm的波长范围内的峰的荧光。
摘要（英）：

Provided are a light-emitting instrument and an image display device utilizing an AlON phosphor and having wide color gamut. The light-emitting instrument includes an emission source emitting light having a wavelength from 410 nm to 470 nm and a phosphor or a light-transmitting body where the phosphor is dispersed, and the phosphor includes an inorganic compound where an AlON crystal, an AlON solid solution crystal, or an inorganic crystal having a crystal structure identical to AlON includes at least Mn, an A element(a monovalent metal element) if necessary, a D element (a divalent metal element) if necessary, an E element (a monovalent anion) if necessary, and a G element (one or more elements other than Mn, the A, Al, O, N, the D, or the E) if necessary, and emits fluorescence having a peak wavelength from 515 nm to 541 nm upon irradiation of an excitation source.
