Embodiment 1
[0020] By composition 38.4ZnF 2 -40P 2 o 5 -10SnO 2 -10In 2 o 3 -1.6Ag (mol%), weighed ZnF 2 、H 3 PO 4 , SnO 2 、In 2 o 3 and AgNO 3 powder raw material. ZnF 2 、H 3 PO 4 and AgNO 3 The raw material powder is mixed evenly in an agate mortar, placed in a corundum crucible, melted in an air atmosphere at 1150°C for 45 minutes, poured the glass melt into a copper mold to form a glass block, and then used an agate mortar It is crushed and ground into powder. glass powder with SnO 2 、In 2 o 3 Mix the powder raw materials evenly in an agate mortar, place them in a corundum crucible, and melt them in an air atmosphere at 1000°C for 45 minutes. Pour the glass melt into a copper mold to form a glass block. After surface grinding, Polished to make a transparent glass sheet.
[0021] like figure 1 As shown, XRD analysis shows that the glass sample is an amorphous phase. The silver quantum clusters in the glass can be detected by transmission electron microscope, abso...
Embodiment 2
[0023] By composition 29.9ZnF 2 -55P 2 o 5 -10SnO 2 -5In 2 o 3 -0.1Ag(mol%), weighed ZnF 2 、H 3 PO 4 , SnO 2 、In 2 o 3 and AgNO 3 powder raw material. ZnF 2 、H 3 PO 4 and AgNO 3 The raw material powder is mixed evenly in an agate mortar, placed in a corundum crucible, melted at 1150°C in an air atmosphere for 30 minutes, poured the glass melt into a copper mold to form a glass block, and then used an agate mortar It is crushed and ground into powder. glass powder with SnO 2 、In 2 o 3 Mix the powder raw materials evenly in an agate mortar, place them in a corundum crucible, and melt them in an air atmosphere at 1000°C for 30 minutes. Pour the glass melt into a copper mold to form a glass block. After surface grinding, Polished to make a transparent glass sheet.
[0024] XRD analysis shows that the glass sample is amorphous phase. The transmission electron microscope photo of the glass shows that there are a large number of sub-nanometer silver quantum clus...
