Cyanine dye excimer formation in nanoporou SiO2 matrices
Institute for Scintillation Materials, STC "Institute for Single Crystals", National Academy of Sciences of Ukraine, 60 Lenin ave., 61001 Kharkiv, Ukraine
Novel red-shifted band has been observed in luminescence spectra of a cyanine dye embedded into nanoporous SiO2 matrix.
That band is concentration dependent and disappears at cooling to low temperature. It has been associated with the dye excimer formation
due to strong interaction with the pores surface.
