Copper(I) Halide Nanoparticle-dispersed Glasses Prepared by Copper Staining

Abstract: Copper(I) chloride and bromide nanoparticle-dispersed glasses were prepared by means of a conventional copper staining. The staining was performed by the following process: copper stain was applied on the surfaces of Cl−- or Br−-ion-containing borosilicate glasses, and the glasses were heat-treated at 510 °C for various times. Typical exciton bands observed in the absorption spectra of the glasses after the heat treatment indicated that CuCl and CuBr particles were formed in the surface region of the glasses. … Show more

“…We have already discussed the first point using the Ostwald ripening model and assuming a reversible formation reaction of CuBr [28]. At the glass surface, CuBr particles of smaller size and therefore with higher interfacial free energy will decompose to Cu + and Br À ions.…”

“…For instance, these glass filters are effective for complete removal of UV radiation in bright light sources used in multimedia equipment such as projectors. Several years ago, we reported a new preparation method for copper(I) halide nanocrystallite-doped glasses for use in this area [27,28], in which copper ions are incorporated into halide ion-containing glasses by means of staining, resulting in the precipitation of copper(I) halide nanocrystallites in the glass surface region. This staining method is a conventional and convenient way of coloring glass [29][30][31][32][33] and provides a possible low-cost preparation method for copper(I) halide nanocrystallite-dispersed glasses.…”

“…In these experiments, the size distribution of the CuBr nanoparticles was also estimated by the change in the peak position of the exciton absorption along the depth. It was shown that the mean particle size decreased with depth gradually around the surface and rapidly at the deeper region [6].…”

“…We have shown that the copper halide nanoparticle-dispersed glasses are easily prepared by the incorporation of copper ions into glasses containing halide ions using a staining process [6,7]. This method provides glasses in which copper halide nanoparticles are uniformly dispersed along with the glass surfaces even though the surfaces have a curvature as with lenses.…”
