Kinetic approach to hyper-doped optical quality thin films

Efficient and benign doping of thin films is key for materials applications and sensor development. Herein, an alternative method of doping is presented where R6G is loaded to an evolving silica thin film. Dopant loading is markedly enhanced and doping can be carried out under relatively benign conditions. The film exhibits outstanding optical quality while its mechanical strength is well-preserved. Early results show diffusion and encapsulation can be tunable.
