| Abstract: | We evaluated energy transfer probe for the characterization of luminescent photonic crystals morphology. It demonstrates a monomolecular filming of fluorescent chelated complexes inside photonic crystal voids. Either direct fluorescence quenching of excited fluorescent donors by the acceptors in case of low concentration of fluorescent centers or fluorescence quenching accelerated by energy migration over fluorescent donor ions in case of 100% of sites occupied by donors is demonstrated in 2D space contrarily to the powder samples of the same complexes where energy transfer occurs in 3D space. |
