One commercially available series of NIR-emitting QDs are lead sulfide (PbS) QDs. Their tuneable emission characteristics are controlled by capping with amphiphilic molecules, which aid the stabilisation of small-sized nanoparticles, preventing uncontrolled growth. In this application note, the photoluminescence spectra of NIR PbS quantum dots are measured in three organic solvents using the FS5 Spectrometer equipped with an NIR InGaAs detector.
