By conventional melt-quenching, we have prepared novel optical amorphous borate-based glass sample series of B2O3-ZnO-TiO2 host materials to investigate their optical properties and microstructure. Following the successful preparation, the density ρ and molar volume Vm of the samples were calculated by the Archimedes principle. In addition, microstructural and optical properties of the materials were determined by the experimental techniques, such as the Fourier transform infrared, Raman, X-ray diffraction, scanning electron microscopy, and UV-vis absorption techniques. The microstructure of the prepared borate-based optical glass materials shows two crystalline phases for various glass compositions, such as titanium oxide TiO2, and zinc borate Zn3(BO3)2. Finally, the direct energy band gaps were 3.5, 3.55, and 3.6 eV for the xZnO contents (x=45, 50, and 55 mol%), respectively.
