Synthesis and optical properties of glass with cadmium sulfide nanoparticles

Formation of CdS nanoparticles in the matrix of silicate glass and its optical properties

“…4,5), in the case of particles of the aver age diameter of 4.8 nm and a volume concentration of about 0.2%, a homogeneous volume filling by the CdS nanoparticles with an optimal dielectric interlayer of 15 nm between them takes place. Based on the results obtained in the present work and in [13,15,16], one can suggest the following scheme of the process of the formation of a composite material from silicate glass doped with CdS. A solution oversaturated with CdS is formed upon the cooling of the melt.…”

“…Earlier, a single stage treatment was used to for mate the CdS phase in the silicate glass matrix [13,15,16]. In the sources in the literature, one can often find the application of multistage thermal treatment, which enables one to separate the process of the nucle ation and growth of the particles of the new phase, and, therefore, to control the sizes and dispersion of the growing centers [14,[19][20][21].…”

“…In our earlier works [13,[15][16][17][18], we found the opti mal conditions of high temperature melting of the sil icate glass doped with CdS, as well as its tempering and low temperature isothermal annealing, in order to fabricate glass with the average diameter of the CdS nanoparticles of up to 9 nm.…”

“…OBJECTS AND METHODS OF STUDY Samples of silicate glass, whose composition was earlier used in the synthesis of CdS nanoparticles in an amorphous matrix, have been investigated [13,15,16]. The contents of the main glass components were as follows (wt %):…”
