Abstract: In order to improve the shielding range of Bi2O3-B2O3-ZnO glass coating in long-wave ultraviolet, and increase its surface hardness and modulus to achieve better protective effect, CeO2 doped Bi2O3-B2O3-ZnO glass coating was prepared. The surface morphology of the coating was evaluated by DSC, SEM, Raman, FTIR, XPS and other test methods. The effects of different CeO2 doping concentrations on the structure, optical and mechanical properties of Bi2O3-B2O3-ZnO glass coating were studied. The results show that when the doping concentration of CeO2 is 0%~1.0% (molar fraction), the microhardness of coating reaches 6.9 GPa and the modulus reaches 84.0 GPa. When the CeO2 doping concentration is 1.0%~2.5%, the polarization of Ce4+ and Ce3+ contained in CeO2 reduces the microhardness and modulus of coating. At the same time, due to the change of glass structure, the conversion between Ce4+ and Ce3+ is promoted, and the ultraviolet shielding band of coatings with different CeO2 doping concentrations is significantly different.
