Infrared absorption spectroscopy measurements for a number of Na-borosilicate glasses containing AgBr and Cu

O were carried out in order to elucidate the structure of these glasses and the forms in which the transition metal ions exist in it. The raw materials used were of chemically pure grade and were finely pulverized. The temperature of the melting was 1,450 °C for 2 h and the samples were then annealed at 480 °C. The prepared glasses studied were then heat treated at 600 °C for 1 h and cooled inside the furnace. The absorption measurements in the Infrared region of the spectrum were recorded in range of (4,000–400) cm

using a Jacso FT-IR 300E Infrared spectrophotometer for all glasses studied. The experimental results obtained showed characteristic variations of the position and intensity of the absorption bands with the glass composition. The effect of the different transition metal oxides on the deformation of the groups present was investigated.
