Figure 9.

Absorption and fluorescence spectra of electrodeposited CuSCN/RB hybrid thin film (solid lines), solid RB thin film prepared by spin coating (dashed lines), and 20 μM RB solution in ethanol (dotted lines). The excitation wavelength for the film samples and the solution were 535 and 530 nm, respectively. The fluorescence spectrum of the RB solution is attenuated for better comparison with other spectra because it is far stronger than the other samples.
