Abstract:Smart filtering of optical radiation involves a combination of advanced materials, optical components, and control methods to accurately tailor the propagation of light. Here, we propose a tunable optical filter by combining the absorptive nonlinearity in platinum nanoclusters and bandgap engineering in Bragg mirrors. Multilayer stacks of polyvinyl carbazole and cellulose acetate, embedded with platinum nanoclusters, are created using the spin-coating method. The improved nonlinear absorption dynamics of these… Show more
