Fabrication and Properties of Pr³⁺-Doped Lithium Gadolinium Borate Glasses

Abstract:

Pr³⁺-doped Li₂O – Gd₂O₃ – B₂O₃ glasses (LGBO glass) with the formula 60Li₂O:10Gd₂O₃:(30-x)B₂O₃:xPrO₃ were fabricated using melt quenching technique. The five glass samples with different concentrations of Pr₂O₃ were prepared under atmospheric pressure. The samples were investigated on their properties: absorption and photoluminescence. All absorption bands are increase with increasing of Pr³⁺ content. The emission spectra were measured with 446 nm light pumped by xenon lamp. The maximum luminescence intensity was observed at x = 0.50 mol% andthe CIE color coordinates showed the bluish purple emission light for this concentration.
