Influence of Dy3+ in physical and optical behavior of calcium sulfate ultra-phosphate glasses
To examine the influence of trivalent dysprosium ion (Dy3+) on physical and optical properties prepared by melt quenching method. The samples composition of 20CaSO4 (80 - x) P2O5 - xDy2O3, where x = 0.1, 0.2, 0.3, 0.4 and 0.5mol% were prepared and analyzed. Materials were characterized by X-ray diff...

| description | To examine the influence of trivalent dysprosium ion (Dy3+) on physical and optical properties prepared by melt quenching method. The samples composition of 20CaSO4 (80 - x) P2O5 - xDy2O3, where x = 0.1, 0.2, 0.3, 0.4 and 0.5mol% were prepared and analyzed. Materials were characterized by X-ray diffraction, UV visible and photoluminescence spectroscopy, amorphous nature of the samples was confirmed by X-ray diffraction technique, UV-Vis for optical measurement and luminescence for excited state dynamics. The UV absorption spectra of the glass sample correspond to 6H11/2 (1673 nm), 6H9/2 (1262 nm), 6F9/2(1087 nm), 6H5/2 (899 nm), 6F5/2 (796 nm), 6F3/2 (753 nm), 6G11/2 (422), 4I13/2 (384) and 6P7/2 (347).The physical properties comprise of glass density, molar average molar volume, ion concentration, dielectric constant and molar refractive index was determined. The band gap (Eopt), Urbach energies (ΔE) and refractive index lie in range and decreases with increase in Dy3+ concentration. Therefore, Dy3+ compositional changes were examined and indicate that dysprosium phosphor could serves as a potential candidate for optical application as laser is included. |
