We report the critical optical properties such as Average Visible Transmittance (AVT), colour, Color Rendering Index (CRI), and Correlated Color Temperature (CCT) of a multicomponent glass system with a nominal composition of 50TeO2–30B2O3-(20-x)Li2O-xCeO2(x=0,0.5,1,2,3,4,5,10,15,20mol%). Various advanced theoretical approaches as well as calculations are utilized in terms of determining the optical properties of studied glasses. The maximum transmittance and AVT values of the glass system exceeded 80% and 79.59%, respectively. The colour coordinates are found extremely near to D65 and the achromatic point without CeO2contribution. According to our results, the current system has a promising ability to be utilized for coloured window applications in terms of both AVT and colour with 2% CeO2doping. Our results showed that, the CeO2additive is able to move the glass colour straight into the red spectrum by shifting the transmittance spectrum to the long-wavelength portion of the visible spectrum. With 10% CeO2doping, opacity in the visible area and permeability in the NIR region are obtained, and the CCT value changes from 5002K to 2560K. It can be concluded that a filter system with modifiable NIR or red optical characteristics may be produced through the CeO2alterations in borotellurite glass systems.
