A representative of the methodology: first，the clean surface of the soda-lime-silicate glass covered on 600℃ tin molten, Sn-x%Cu molten and Sn-x%Cu-y%P molten for 10 minutes , respectively and then air-cooled at ambient temperature. In the meantime, the metallic atoms of the molten will be heterogeneous nucleated and grew on the surface of the soda-lime-silicate glass, thus a thin film was formed. The experimental results show that the morphology of the thin film on tin molten, oxidized tin molten, oxidized Sn-x%Cu molten and oxidized Sn-x%Cu-y%P molten system are tin dendrite crystals, polygonal tin oxide crystals and polygonal crystals of tin oxide mixing with flake tin oxide doped with phosphorus crystals and lumps Sn3(PO4) 2 crystals,respectively. It is worth noting that the copper atoms will not adhered on the surface of the soda-lime-silicate glass, but they will help the tin oxide crystals formed on the surface of the sodium-calcium glass. Through photo spectrum analysis, These films have a obviously absorption peaks in the UV region, which the thin film formed on the oxidized phosphor bronze molten has a highest absorption peak value, next is the oxidized bronze molten, followed by oxidized tin molten is minimum.
