Abstract:

Complexes of Mn2+-doped ZnS quantum dots with chlorin e6 molecules have been created in which photoexcitation energy transfer from the quantum dots to the chlorin e6 molecules is observed. The optical properties of these complexes have been investigated by steady-state absorption and luminescence spectroscopy. It is established that the photoexcitation energy-transfer efficiency is about 40%. An increase of the relative concentration of chlorin e6 in the complex reduces the luminescence quantum yield of the chlorin e6 associated in the complex with the quantum dots.
