Study on the Physical, Optical and Luminescence Properties of the Cr-Doped Recycled Waste Glass

Abstract

The rapid economic growth in recent years has led to the use of glass material in many activities, resulting in a large amount of glass waste. The efficient use of waste glass recycling has gained increasing attention. Researchers propose a method for recycling waste glass to reduce glass manufacturing costs and investigate the physical, optical, and luminescence properties of chromium oxide-doped glass with the stoichiometry of (35-x) B₂O₃: 35SiO₂ (use waste glass as SiO₂): 12Na₂O: 7.9CaO: 0.1Sb₂O₃: 10BaO: xCr₂O₃ when x = 0.00 to 0.05 mol%. Glass was synthesized using the melt quenching at 1,200 degrees Celsius for 3 h. Archimedes’ principle and the Abbe refractometer were used to calculating density and refractive index decrease with the addition of 0.01 mol% of Cr³⁺ concentration. At room temperature, absorption spectra were analyzed using a UV-VIS-NIR spectrometer exhibiting two broadband at 438 and 625 nm intense bands, and the luminescence properties of the Cr³⁺ glasses system were investigated using an excitation wavelength of 567 nm, with luminescence peaks observed around 750 nm. CIE L* a* b* shows the green color.
