We have been investigating complexes composed of nano-sheet with anionic charges such as clay nanosheets and molecules such as cationic organic dyes. Photochemical properties of organic dyes are much affected by the complex formation with nano-sheet in many cases. Especially, a strong fluorescence enhancement behavior of dyes was frequently observed on the nano-sheet surface. Based on the mechanism, we name this unique effect "S-Fixation Induced Emission (S-FIE)". The examples for fluorescence enhancement are shown and the mechanism is discussed in detail.
