Abstract:
1. A method of manufacturing fluorescent material-dispersed glass, comprising: performing production of a fluorescent material-dispersed gel utilizing sol-gel reaction and acid-base reaction by preparing a fluorescent material-dispersed sol containing silicon alkoxide, metal chloride and/or metal alkoxide, and fluorescent material while avoiding reacting of the fluorescent material with the sol, and subsequently gelling the fluorescent material-dispersed sol; and performing production of a fluorescent material-dispersed glass by heating the fluorescent material-dispersed gel while avoiding reaction of the fluorescent material with the glass, wherein the production of the fluorescent material-dispersed sol includes preparing a precursor sol using the silicon alkoxide, the metal chloride and/or metal alkoxide, and water, and preparing the fluorescent material-dispersed sol by dispersing the fluorescent material in the precursor sol after controlling viscosity of the precursor sol to be in the range of 100 to 10000 mPa·s.
