Fig. 2From: Air-stable and ultrasensitive solution-cast SWIR photodetectors utilizing modified core/shell colloidal quantum dotsXRD patterns of PbS, PbS/CdS (thin shell), and PbS/CdS (thick shell) QDs. The JCPDS card files (05-0592, blue line) for PbS and (01 089 0440, green line) for CdS are shown below the spectra for identificationBack to article page
