A new red-emitting CPL/TADF derivative is reported. A monomeric form is compared to its chiral dimeric counterpart to unravel the impact of dimerization on TADF properties. Circularly polarized fluorescence and phosphorescence are also investigated.

Chiral surface ligands have often been employed to impart optical activity to metal nanoclusters, metal nanoparticles and semiconductor nanocrystals. They are considered to form a chiral structure to a certain degree whereas the effect of such chiral

To advance the development of atomically thin optoelectronics using two-dimensional (2D) materials, engineering strong luminescence with a physicochemical basis is crucial. Semiconducting monolayer transition-metal dichalcogenides (TMDCs) are candida

Alignment of carbon nanotubes (CNTs) in CNT/polymer composite films is an attractive technique to obtain improved electrical, mechanical, and thermal properties. However, their alignment method is still confined to small laboratory scale sample prepa

The Sr2MgSi2O7:Eu2+,Dy3+ materials were prepared with a solid state reaction and their microscopic structure (at 295 K only) and luminescence were studied at selected temperatures between 150 and 295 K. Undisturbed Sr crystal planes were common in th

We present an atomic picture of quantized circulation of repulsively interacting Bose particles in a one-dimensional ring. The flow of the particles along the ring is quantized and metastable at sufficiently low temperatures, due to the interparticle

We study a model of three mutually interacting identical particles confined in a onedimensional space, giving correlated states without one-body approximations. Certain types of quantum dynamics are illustrated with the model: quantum tunneling of po
