A solid state method of producing inorganic nanoparticles using glass is disclosed. The nanoparticles may not be formed until the glass is reacted with or degraded by contact with a fluid in vivo or in vitro.

Provided is a process for producing a wavelength conversion member which can suppress the reaction between inorganic nanophosphor particles and glass to suppress the deterioration of the inorganic nanophosphor particles, and the wavelength conversion member. The process for producing a wavelength conversion member includes the steps of: preparing inorganic nanophosphor particles 1 with an organic protective film formed on respective surfaces thereof; and mixing the inorganic nanophosphor particles 1 with glass powder and firing a resultant mixture in a temperature range where the organic protective films remain as retained films 3.

A microheater comprises an optical fiber including a rare earth-doped glass core surrounded by a glass cladding. The rare earth-doped glass core comprises a rare earth dopant at a concentration sufficient for luminescence quenching such that, when the rare earth dopant is pumped with light at an absorption band wavelength, at least about 90% of absorbed pump light is converted into heat.

The present disclosure provides a wavelength conversion glass, a method for manufacturing the wavelength conversion glass, and a light emitting device including the wavelength conversion glass. The wavelength conversion glass includes a TeO.sub.2B.sub.2O.sub.3ZnOBaO-based transparent glass containing tellurium dioxide (TeO.sub.2), boric oxide (B.sub.2O.sub.3), zinc oxide (ZnO), and barium oxide (BaO); and phosphor micro-particles dispersed in the transparent glass.
