Binary calcium phosphate and barium phosphate glasses corresponding to xCaO-(100 ร x)P 2 O 5 and xBaO-(100 ร x)P 2 O 5 , respectively, have been prepared in the range of 20 6 x 6 50. Assessment of the optical and thermal properties reveal that refractive index (n) and glass transition temperature (T
Vanadium barium borate glasses were prepared by a normal melt quench technique. The infrared spectra of these V 2 O 5 ร BaO ร B 2 O 3 glasses were recorded over a continuous spectral range (400-4000 cm ร1 ) in an attempt to study their structure systematically. The conversion from three-to four-fold
