Structural and luminescence study of antimony-zinc borophosphate glass doped with iron

Abstract

Antimony zinc borophosphate glass were prepared with the composition of 20ZnO-30B(2)O(3)-xP(2)O(5)-(50-x)Sb2O3-2Fe(2)O(3) (0 <= x <= 50 mol%) using the melt quenching method. The starting materials were mixed and preheat for 30 minutes and transfer into high temperature furnace for melting. The structure of samples were measured using Fourier-Transform Infrared (FT-IR) Spectroscopy. The spectra showed that network structure in the samples are mainly based on P=O, PO2, P-O, B-O-B and B-O units. With increasing P2O5 content, the vibration of P-O tends to shift towards lower wavenumber. Meanwhile, the luminescence was studied using Photoluminescence (PL) Spectroscopy. The samples were excited at specific wavelengths (265 - 300 nm). The emission profiles were obtained to study the energy transfer process. Luminescence of violet colour from samples were also recorded to correlate with PL results.
