Blueshift of plasmon resonance with decreasing cluster size in Au nanoclusters embedded in silica matrix

S. Dhara, B. Sundaravel, T. R. Ravindran +3

Gold nanoclusters are grown by 1.8 MeV Au++ implantation in silica matrix and subsequent air annealing in the temperature range of 873K-1273K. Post-annealed samples show plasmon re…
