Semiconductor quantum dots for photoluminescence-based gas sensing
Z. Zhao, M.A Carpenter and M.A Petrukhina, University at Albany-SUNY, USA
The photoluminescence (PL) characteristics of semiconductor quantum dots (QDs) and their intrinsic sensitivity to their surrounding environment have made them an attractive material set for sensing applications. However, their development into PL-based gas sensors requires several considerations. Specifically, the QD surface chemistry via manipulation with surface ligand engineering, rational design and control of polymer host chemistry and in situ/ex situ dispersing methods, or polymer-free QD deposition methodologies and sensible introduction of functional substrates all need to be ...
