A luminescent glass includes nanocrystalline semiconductor particles, such as ZnS nanocrystals, and an activator, such as copper, for the particles. The glass is made by depositing the nanocrystalline semiconductor particles and the activator within a porous glass matrix, such as 7930 Vycor.TM. and then thermally activating the glass. The porous glass matrix may be at least partially consolidated or may be allowed to remain porous. The nanometer particle size permits the luminescent glasses of the present invention to be transparent to its luminescent emsissions.
L'invention a pour objet un verre luminescent. Ce verre comprend des particules nanocristallines semi-conductrices, comme des nanocristaux de ZnS, et un activateur, tel que du cuivre, pour ces particules. On réalise ce verre en déposant les particules nanocristallines semi-conductrices et l'activateur dans une matrice de verre poreuse, telle que du 7930 Vycor<TM> et en activant thermiquement le verre. La matrice de verre poreuse peut être au moins partiellement consolidée ou peut rester poreuse. La granulométrie de l'ordre du nanomètre des particules permet aux verres luminescents selon la présente invention d'être transparents aux émissions luminescentes.
