WAVELENGTH CONVERSION MATERIAL, WAVELENGTH CONVERSION ELEMENT, METHOD FOR PRODUCING SAME, AND LIGHT EMITTING DEVICE
The purpose of the present invention is to provide a wavelength conversion material and a wavelength conversion element which, when irradiated with light from a high-power LED or LD, are capable of suppressing degradation of luminous intensity and dissolution of constituent materials over time; a method for producing the wavelength conversion material and the wavelength conversion element; and a light-emitting device. The wavelength conversion material (10) is characterized by comprising a matrix (1) having a skeleton composed of an inorganic material (3) and a transparent material (4) filledin a hollow part formed by the skeleton, and phosphor particles (2) dispersed in the matrix (1), and the inorganic material (3) having a higher thermal conductivity than the transparent material (4).
本发明的目的在于提供在照射大功率的LED或LD的光时，能够抑制经时的发光强度的降低和构成材料的溶解的波长转换材料和波长转换元件、以及它们的制造方法和发光装置。一种波长转换材料(10)，其特征在于，包含基质(1)、和分散在基质(1)中的荧光体颗粒(2)，基质(1)具有由无机材料(3)构成的骨架、和填充在由骨架形成的空孔部的透明材料(4)，且无机材料(3)具有比透明材料(4)高的热传导率。
