This study focuses on the control of the light matter phenomenon in the visible wavelength range. In order to absorb the incoming light, silver nanospheres and nanoprisms are chemically synthesized and embedded in a non-absorbing and transparent polymer host matrix. By combining nanospheres and nanoprisms in the same thin film layer, the plasmonic absorption peaks of nanospheres and nanoprisms are combined. Aggregates of nanospheres and nanoprisms lead to a redshift and broaden the absorbance peak, as expected by finite difference time domain simulations.
