Abstract:
The present invention provides a thin-film fluorescent material in which semiconductor nanoparticles in a stable condition maintain a high fluorescence quantum yield and can be held at a high concentration in a glass matrix. The present invention also provides optical devices using the thin-film fluorescent material, such as high-brightness displays and lighting systems. The present invention relates to a fluorescent material, in which semiconductor nanoparticles with a fluorescence quantum yield of 15% or more and a diameter of 2 to 5 nanometers are dispersed in a glass matrix at a concentration of 5×10−4 mol/l or more and a method for manufacturing the same.
