Thermal imprinting conditions of low-softening tin phosphate glass with a composition of 67 mol% SnO-33 mol% P2O5 were investigated using three processing parameters of temperature, imprinting pressure, and holding time. Fabrication conditions of a micro square grid (SG) pattern with a similar depth of silica mold (~120 nm) were optimized. AFM observations confirmed that the 700 nm × 700 nm SG pattern with ~120 nm depth could be formed with good reproducibility.

A new series of chalcogenide glasses in the Cu 2 S-Sb 2 S 3 system was prepared by a conventional meltquenching method. The glassy nature of prepared compositions was proved using X-ray diffraction analysis. The homogeneity and microstructure were evaluated using FE-SEM. Physical properties such as glass transition temperature, crystallization temperature, density, optical transmission and electrical resistivity were measured. The results show that the Cu-Sb-S glasses form in the composition region of 21.5 and 24.5 mol% Cu 2 S. The glass transition temperature is 185˚C and the optical transmission window is lying between 0.9 and 15 μm for the representative 22.5Cu 2 S -77.5Sb 2 S 3 glass sample. The result of electric resistivity indicates that the change of electric resistivity is about 3 orders by the crystallization of glass.
