A Study of Optical Properties of Tetraborate Glasses Containing CaO, MgO & BaO
Glasses with compositions (100-x) % Na2B4O7–x % MO (X=10,20,30,40) where (M) is Ba, Mg and Ca, are prepared using conventional melt quenching method. X-rays diffractions are performed. The result of (XRD) confirm the amorphous nature of the samples. The measured density increases with increasing con...

| description | Glasses with compositions (100-x) % Na2B4O7–x % MO (X=10,20,30,40) where (M) is Ba, Mg and Ca, are prepared using conventional melt quenching method. X-rays diffractions are performed. The result of (XRD) confirm the amorphous nature of the samples. The measured density increases with increasing content of BaO, MgO & CaO in glass network. The position and shifting rate of absorption edge, optical band energy (Eopt) and band tails energy (Eo) were investigated. The Eopt and Eo values of all glasses studied in this work were found to be comparable with the values corresponding to some semiconductors. The structure of the glasses was investigated by means of IR spectroscopy. It found from the experimental results of IR spectra that the groups (BO3)- and (B2O7)- are dominant the structure of these glasses. Also It is found that the shifting in band position is small with increasing of (Ba, Mg, Ca) oxide in the glass network. |
