Photo-induced flexible semiconductor CdSe/CdS quantum rods alignment
Wanlong Zhang,Julian Schneider,Maksym F. Prodanov,Valerii V. Vashchenko,Andrey L. Rogach,Xiaocong Yuan,Abhishek K Srivastava +6 more
TL;DR: Researchers developed a photo-induced alignment technique to orient CdSe/CdS quantum rods in a liquid crystal polymer matrix, creating large-scale, anisotropic patterns with potential applications in security and optoelectronics.

Cascade upconversion of photoluminescence in ensembles of II-VI semiconductor nanocrystals
E. Malainho,Joao Santos,Mikhail Vasilevskiy,Sergej Filonovich,Yury P. Rakovich,Andrey L. Rogach +5 more
TL;DR: In this paper, the theory of the thermally activated photoluminescence upconversion, also known as anti-Stokes photolumininescence (ASPL), based on the quantum dot (QD) polaron effect and explaining all the principal features of the ASPL in colloidal solutions of chemically grown nanocrystals (NCs), was presented.

Nanothermometry: Temperature-Dependent Exciton and Trap-Related Photoluminescence of CdTe Quantum Dots Embedded in a NaCl Matrix: Implication in Thermometry (Small 4/2016)
TL;DR: Solid-state powders of CdTe quantum dots embedded in a NaCl matrix are applied as a highly sensitive probe for luminescence thermal imaging and sensing across a wide range of temperatures by A. L. Rogach and co-workers, showing how the emission color changes over the whole spectral range from green to red as a function of temperature.
