Abstract

Ion manipulation using micro-probe has been performed to fabricate the nano-scale dots on/or in the glass. Soda-lime-silica glass was subjected to the treatments. Two types of the manipulation treatments were carried out using various probes and electrical conditions. In the Na-extraction treatment, the thick needles and/or STM tips were used as a cathode. At 250°C, Na⁺ ions were extracted from the inside of the glass towards the cathode tip, and electrochemically reduced to Na-metal. Na-metal are held at the tip/glass interface as liquid state, and grew with the treatment time. After the treatment, they formed the micrometer-size dots of fodium compound on the glass surface, and their size was dependent on the total charge conducting through the tip. In the Ag-migration treatment, Ag-metal probes were prepared and used as an anode at 200°C. Ag atoms on the tip were oxidized to Ag⁺ ions and migrated into the glass. They could be optically recognized using the luminescence from Ag⁺ ions under the UV irradiation. a lot of Ag-metal dots with the size 100-300nm were also formed on the glass surface. They are considered to be transferred from the tip of Ag-metal probe onto the glass surface. The size of the Ag⁺ migrated region was dependent on the total charge of the treatment, and the available small size was found to be defined by the apex of the probe tip. The observed phenomena in these treatments were explained and the possibility of the formation of nano-scale dots on the glass by ion manipulation was discussed.
