Abstract :
We present some results obtained by steady-state and time-resolved fluorescence analysis of PbS quantum dots in solution and in a porous matrix. Distribution of QDs in the porous matrix was investigated by atomic-force and confocal microscopy to clarify an energy transfer in formed closed packed structures. Hardware and software for fluorescence measurements in near infrared region also are discussed.
