Figure 3

(a) FL spectra for RhB-infiltrated monolithic 3D CPhCs of E and F, heterostructures of E-F and F-E and double heterostructures of E-F-E and F-E-F. Control is RhB on aPS. (b) FL enhancement factors for all samples, measured as the ratio of FL intensity maxima between the sample and the control. (c) The effect of F layer thickness on RhB FL intensity in E-F-E double heterostructure; (d) The effect of E layer thickness on RhB FL intensity in E-F-E double heterostructure.
