Formation principles, mechanisms of photoluminescence quenching and surface photochemistry are discussed for nanocomposites based on semiconductor CdSe/ZnS quantum dots with attached porphyrins or perylene bisimides (steady-state, picosecond time-resolved spectroscopy and single molecule spectroscopy, 77-300 K, solutions and rigid films).
