Structural and photoluminescence properties of europium oxide doped fluoroborate optical glasses

A sequence of zinc-magnesium-lithium-fluoroborate (ZMLB) optical glasses doped with different Eu 3+ concentrations were synthesized through melt quenching technique. The non-crystalline characteristic the was proved by X-ray diffraction studies and FT-IR transmittance spectra have been used to study various vibrational bands in glass systems. photoluminescence characteristics studied under an excitation 393 nm it exhibits four emission peaks around at 590, 615, 654 700 assigned 5 D 0 → 7 F 1 , 2 3 4 electronic transitions ion, respectively. Color chromaticity values estimated from luminescence for all samples these parameters indicate red color region cold light emission. All results suggest that ions ZMLB are a potential candidate generation 615 explore new material solid state emitting diode applications.
