Improvement of mechanical strength in Y3+/La3+ co-doped silicate glasses for display screen

Y2O3 and La2O3 co-doped silicate glasses were prepared by conventional melt-quenching method. The effects of Y2O3 and La2O3 contents on the structural, thermal and mechanical properties of glass samples were investigated by X-ray diffraction (XRD), Differential scanning calorimetry (DSC) and Fourier Transform Infrared Spectroscopy (FTIR). The results showed that the prepared glass samples exhibited excellent mechanical properties and thermal stability. The hardness, elastic modulus and ΔT reaches 860HV, 108 GPa and 299 °C, respectively. Compared with the reported glasses for this type, these values were increased by approximately 19.5%, 28% and 8.7%, respectively. In addition, the transmittance of all glass samples exceeds 90% in visible spectra range. The above results indicate that the prepared glass samples can be applied to the fields of architectural glass, automotive windshield and screen of electronic products.
