摘要

Embedded silver nanostructures with different shapes and sizes are grown in Si substrates by chemical vapor deposition (CVD) method. Systematic study of their surface-enhanced Raman properties is performed. Influence of shape, size, and coverage of the nanoparticles on the average enhancement factors is calculated with the help of standard analyte molecules viz. crystal violet and Rhodamine 6G to optimize the substrates for future sensing applications.
