Accelerated Charge Transfer in the AgInS-Polymer Layer-by-Layer Films.

In this work, the luminescence properties of AgInS colloid nanoparticles in solution and in films were investigated and compared. Decay time of fast and slow relaxation processes differ by about an order of magnitude. Both components are significantly reduced in films compared to the corresponding contributions in colloids that hint towards charge carrier transfer between AgInS particles enhanced in the films.
