Excitonic emission of hybrid lead iodide perovskite single crystals.

Since 2012, hybrid organic perovskites (HOPs) represent a “material breakthrough” for photovoltaïcs and more broadly, HOPs have also high potentialities for light-emitting devices such as electroluminescent diodes and lasers. Improvement of the…

Linear and Third-Order Nonlinear Optical Properties of Triazobenzene-1,3,5-triazinane-2,4,6-trione (Isocyanurate) Derivatives

The synthesis of three new isocyanurate derivatives 2-X (X=NO2, H, NMe2) with azobenzene arms terminated by various X substituents is reported, and their linear and nonlinear absorption properties are studied. It is shown that mixtures that contain…

On the temperature dependence of the quenching by a few defects of TADF materials. Triplet versus Singlet FRET

Thermally Activated Delayed Fluorescence (TADF) molecules contribute to the light emission of an optoelectronic device from both their singlet and triplet states. But the quenching limits these benefits. In the case of cationic (NHC)Cu(I) complexes…

Circularly polarized OLED based on thermally activated delayed fluorescence molecules

Organic Light-Emitting Diodes (OLEDs) have already entered the mass production market in small size displays (smart phone…) or larger display devices for OLED televisions. However, the request in the market continues to grow for low-power…

Spirobifluorene Regioisomerism: A Structure–Property Relationship Study

The present works report the first structure–prop-erty relationship study of a key class of organic semiconductors , that is, the four spirobifluorene positional isomers possessing a para-, meta-or ortho-linkage. The remarkable and surprising impact…

An efficient tetrazine photoluminescent layer used for organic solar cells down shifting

This work reports a new material used as photo luminescent layer in inverted organic solar cells. We have studied the fluorescence and the optical properties of tetrazine molecules included in the layer. The molecules are used at a small to average…
