Abstract
The structural and electrical properties of some CdI2 doped silver borophosphate glasses and glass nanocomposites of compositions 0.2CdI2 - 0.8(0.50Ag2O - 0.50(xB2O3 - (1 - x)P2O5)), prepared by the melt quenching method, are reported in this paper. The X-ray diffraction study reveals the amorphous nature for the compositions x = 0-0.80 and partial crystalline nature for the composition x = 1. However, the transmission electron microscopic studies reveal the presence of some crystalline phases such as CdI2, β-AgI, and AgPO3 for x = 0-0.80 and β -AgI, Ag3BO3, and CdI2 for x = 1. The FTIR spectra reveal that the BO4 units are predominant for x = 0.20-0.50. The BO3 unit appears beyond the composition x = 0.20, and its population increases with the increase of B2O3 content. The conductivity of the compositions increases (for x = 0-0.60), and the activation energy decreases with progressive substitution of B2O3 in the glass network. However, the conductivity almost saturates for B2O3 rich compositions (for x = 0.60-1). The ion dynamics of the compositions as well as other physical properties such as density, glass transition temperature, etc., have been correlated with the compositional variation of BO4 and BO3 units.
