Semiconductor quantum dots (QDs) and their complexes with organic molecules have been a subject of extensive research during the last couple of decades. In particular, complexes of QDs and

complexes the efficiency of singlet oxygen generation may be significantly increased, as compared with the free tetrapyrroles, due to an efficient photoexcitation energy transfer from the QD to the molecule. QDs have unique optical properties such as a broad absorption spectrum with extremely high
, since the decrease in PL quantum yield (QY) of the tetrapyrroles is usually accompanied by a decrease in efficiency of singlet oxygen generation [4].
In this study we investigate the photophysical properties of QD–Ce6 complexes under variable conditions of formation such as the molar concentration ratio
