Effect of Nature of the Inorganic Salt Matrix on the Optical Properties and Photostability of CdTe/CdS Quantum Dots

  • Published:
Theoretical and Experimental Chemistry Aims and scope

The photoluminescence and photostability of CdTe/CdS nanoparticles encapsulated in matrices of potassium dihydrogen orthophosphate, potassium bromide, calcium carbonate, and barium sulfate were studied. The greatest photostability was found for a composite with a monocrystalline KH2PO4 matrix. This stability is related to the hindered diffusion of oxygen to the implanted CdTe/CdS quantum dots.
