Effect of deformation of a polymer matrix on the optical properties of CdS nanocrystals incorporated into it

Autor: Yury P. Rakovich, S. A. Filonovich, A. A. Gladyshchuk, M. V. Artem’ev

Publikováno v: Journal of Applied Spectroscopy. 67:134-138

A study is made of the photodegradation kinetics of luminescence and absorption of cadmium sulfide nanocrystals incorporated into a plastic polymer matrix. The reversibility effect of photodegradation under mechanical deformation (stretching) of a po

Polaron Effect In Semiconductor Quantum Dots: Impact On The Optical Absorption, Up-converted Photoluminescence And Raman Scattering

Autor: Mikhail Vasilevskiy, R. P. Miranda, S. A. Filonovich, Enrique V. Anda, S. S. Makler

Publikováno v: AIP Conference Proceedings.

Multi‐phonon processes in a model quantum dot (QD) containing a small number of most important electronic states and several optical phonon modes are considered exactly, taking into account both intra‐ and inter‐level interactions. The calculat

Publikováno v: MRS Proceedings. 737

We report on the efficient photoluminescence up-conversion in colloidally synthesized CdTe nanocrystals. We demonstrate that the efficiency of photon energy up-conversion and magnitude of spectral shift can be controlled: (i) by the size of the nanoc
