Abstract
Provided are an inorganic fluorescent nanoparticle composite that can suppress the degradation of inorganic fluorescent nanoparticles when sealed in glass and a wavelength conversion member using the inorganic fluorescent nanoparticle composite. An inorganic fluorescent nanoparticle composite 1 is made up by including: an inorganic fluorescent nanoparticle 2; and an inorganic fine particle 3 deposited on a surface of the inorganic fluorescent nanoparticle 2.
Claims9
An inorganic fluorescent nanoparticle composite comprising:
- an inorganic fluorescent nanoparticle;
- and
- an inorganic fine particle deposited on a surface of the inorganic fluorescent nanoparticle;
- wherein
- a plurality of the inorganic fine particles are deposited on the surface of the inorganic fluorescent nanoparticle to surround the inorganic fluorescent nanoparticle;
- an average particle diameter of the inorganic fine particles is larger than an average particle diameter of the inorganic fluorescent nanoparticles;
- and
- a content of the inorganic fine particles is, relative to 1 part by mass of inorganic fluorescent nanoparticles, 10 parts by mass or more and 10000 parts by mass or less.
