    • Provided is a light-emitting glass which is applicable to, e.g., white illuminators including a light-emitting diode as a light source, and which emits light of a warm white color when irradiated with near ultraviolet light and combines long-term weatherability with high heat resistance; a light-emitting device containing same and a process for producing same. The light-emitting glass includes, as the base glass, borosilicate or silicate glass having a separated-phase structure, whereby the base glass is efficiently doped with, for example, transition metal ion clusters which emit light of a warm white color upon irradiation with near ultraviolet light. With this glass, it is possible to attain increases in excitation wavelength and emission wavelength. The glass thus emits, based on a multiple scattering effect, high-intensity light of a warm white color upon irradiation with near ultraviolet light.
    • 提供了一种发光玻璃,其可应用于例如包括发光二极管作为光源的白色照明器,并且当用近紫外光照射时发出暖白色的光,并将长期耐候性与高 耐热性; 含有该发光装置的发光装置及其制造方法。 作为基底玻璃,发光玻璃具有分离相结构的硼硅酸盐玻璃或硅酸玻璃,由此基底玻璃有效地掺杂有例如在照射时发出暖白色光的过渡金属离子簇 近紫外线。 利用该玻璃,可以获得激发波长和发射波长的增加。 因此,基于多次散射效应,玻璃在近紫外光照射时发出暖白色高强度光。
