The role of CuCl2 in tuning the physical, structural and optical properties of some Al2O3-B2O3 glasses

摘要

To study the effects of copper cations on some properties of a glass system, new glass formulation [75% B2O3 - 5% Al-2 O-3 - (20 - x) % Na2O - (x) % CuCl2], where x = 0.0, 1.0, 2.0, 3.5 and 4.5 mol.% was obtained via melt quenching method. X-Ray Diffraction (XRD) results emphasize the samples amorphous nature. The glasses internal structure was scrutinized via Fourier Transform Infrared Spectroscopy (FTIR). The dependence of density (rho), boron to boron separation (d(B-B)), molar volume (V-m), optical absorbance (A), transmission (T), Urbach energy (E-U), refractive index (n) and metallization criterion (M) on CuCl2 content was scrutinized. The trend of density (rho), boron-boron separation (d(B-B)), molar volume (V-m), optical absorbance (A), Urbach energy (E-U) and refractive index (n) show increasing behavior, while band gap (E-g) and metallization criterion (M) show decrement behavior with CuCl2 content. According to the obtained results (e.g. absorbance), these samples are probable candidates for some optical applications.
