Blue luminescence of Au nanoclusters embedded in silica matrix
S. Dhara, Sharat Chandra, P. Magudapathy +8
Photoluminescence study using the 325 nm He-Cd excitation is reported for the Au nanoclusters embedded in SiO2 matrix. Au clusters are grown by ion beam mixing with 100 KeV Ar+ irr…
Acoustic vibrations of a silica-embedded gold nanoparticle: elastic anisotropy
Daniel B. Murray, S. Dhara, T. R. Ravindran +4
Spherical gold nanoclusters are grown by 1.8 MeV Au++ ion implantation into an amorphous silica matrix and subsequent air annealing at 873 K. Ultraviolet and visible light absorpti…
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…
'Spillout' effect in gold nanoclusters embedded in c-Al2O3(0001) matrix
S. Dhara, B. Sundaravel, T. R. Ravindran +5
Gold nanoclusters are grown by 1.8 MeV Au^\sup{2+} implantation on c-Al\sub{2}O\sub{3}(0001)substrate and subsequent air annealing at temperatures 1273K. Post-annealed samples show…
