resonance and in the photoluminescence emission. The geometry of the goldnanoparticleaggregates determine the strength of the Anderson localization, and hence, the light emission from the aggregates. The photoluminescence lifetime was found to be dependent on the AuNP aggregate geometry and the dielectric
constant of the medium.

The process of localization of waves has been observed in several physical phenomena, such as for excitons in semiconductor nanostructures [1] and
