Abstract
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.
Claims6
A process for producing a wavelength conversion member, the process comprising the steps of:
- preparing inorganic nanophosphor particles with an organic protective film formed on respective surfaces thereof;
- and
- mixing the inorganic nanophosphor particles with glass powder and firing a resultant mixture in a temperature range where the organic protective film is retained.
A wavelength conversion member comprising:
- inorganic nanophosphor particles;
- a glass matrix containing the inorganic nanophosphor particles dispersed therein;
- and
- retained films made of organic protective films that are provided between the inorganic nanophosphor particles and the glass matrix and retained even after having undergone firing.
