Claims13
A solution for forming metal nano particles, comprising:
- a compound having the following chemical formula:
- wherein M is a metal atom of gold (Au), R is (—CH2—)n, F is selected from the group consisting of sulfur (S), nitrogen (N) and phosphorus (P), X is a silyl group, Y represents an oxidation state of the metal atom in the compound of +1, m is a natural number ranging from 1 to 10, and n is a natural number ranging from 1 to 15;
- a solvent;
- and
- a stabilizer for preventing metal atoms from being precipitated in the solvent.
