    Photoluminescence

    Photoluminescence piezo-spectroscopy (PLPS) is a technique that can be conveniently used to determine the stress in alumina-containing material with high resolution, particularly it is a very useful technique to measure residual stress on TGO layers. 65,66 Zhao and Xiao 67 measured the residual stresses in TBCs by PLPS and compared with

    Small molecules with ambipolar transporting properties

    For stable and efficienct organic light-emitting diodes, it is essential to find molecules with high photoluminescent efficiency, little self-quenching and balanced charge transporting properties. Recently, we've designed and synthesized some highly emissive naphtho[2,3-c][1,2,5]thiadiazole (NTD) derivatives and naphtho[2,3-c][1,2,5]selenadiazole (NSeD) derivatives with unusual ambipolar

    Ambipolar Field-Effect Transistor of High Photoluminescent

    An ambipolar field-effect transistor (FET) based on a 1,3,6,8-tetraphenylpyrene (TPPy) single crystal, a highly photoluminescent material, has been successfully fabricated.

    Synthesis, optoelectronic properties and applications

    Followed by the classification of synthesis, we address the ensemble and single particle properties of perovskites from the viewpoints of the confinement and transport of charge carriers or excitons. Further, we correlate the charge carrier properties of perovskite films, microcrystals, nanocrystals and quantum dots with the crystal structure

    Small molecules with ambipolar transporting properties

    The ambipolar transporting properties of the NTDs were explained by Marcus theory with carrier reorganization energies and charge-transfer integrals. We obtained high quality single crystals of 4,9-di(biphenyl-4-yl)-naphtho2,3 -c 1,2,5thiadiazole (NTD02) and 4,9-bis(4-(2,2-diphenylvinyl)phenyl)-naphtho2,3 -c 1,2,5thiadiazole (NTD05).

    The mixed compounds act like a photocarrier concentrator, funneling the charge carriers from high‐bandgap materials to the lowest‐bandgap ones and boosting the external quantum efficiency (EQE) to 8.8% and 11.7% (Figure 6B‐C), respectively. 134, 135 Jiang et al. tuned the “A‐site” cation by using a Rubidium‐Cesium alloyed

    They also have strongly bound excitons, which inhibit free carrier generation. Therefore, they have similarly low mobilities, poor charge transport, and high resistivities of 10 10 to 10 12 Ω cm 19. Solar cells using them as absorbers definitely have the same problem, which is very low J sc ’s and PCEs. It looks that both these two types of

    Synthesis and Characterization of New Photoluminescent

    We report on the synthesis and the characterization of a new class of segmented polyethers POC containing the oxadiazole and carbazole units. The polymers exhibit a high thermal stability, high glass transition temperatures, and good solubility in common organic solvents, despite the extended aromatic portion in the main polymer chain. The synthetic procedures are simple, and no acid side
