Journal ArticleDOI
Surface Modification of a Hydrogen-Bonded Pigment: A Fluorescence Spectroscopy Study
TL;DR: Evidence for surface dissolution that occurs during the mixing of solids is presented and the spectral signatures of monomers and hydrogen-bonded aggregates of the pigment are quite distinct, as revealed by fluorescence excitation and emission spectra.
Journal ArticleDOI
Photo-induced oxidation of N-vinylcarbazole in a functionalized oil-in-water microemulsion
TL;DR: In this paper, the photoprocesses of N-vinyl carbazole (NVC) solubilized in the interior of an oil-in-water microemulsion (CTA-ci, hexadecyltrimethylammonium counter ion) functionalized by an oxidizing agent, S2O2−8, were studied using ruby laser and spectrofluorimeter techniques.
Journal ArticleDOI
Excited state electron and energy transfer of a highly fluorescent heterocyclic dye: a laser flash photolysis study of 2,5-dimethyl-3,6-diphenylpyrrolo[3,4-c]pyrrole-1,4-dione
TL;DR: In this paper, the triplet and singlet state properties of the title compound were investigated and electron transfer from the singlet excited state to methyl viologen in acetonitrile produced the corresponding free radicals which recombine with second-order kinetics.
Journal ArticleDOI
Combined Vacuum Evaporation and Solution Process for High‐Efficiency Large‐Area Perovskite Solar Cells with Exceptional Reproducibility
Liguo Tan,Junjie Zhou,Xing Zhao,Siyang Wang,Minghao Li,Chao Jiang,Hang Li,Yu Zhang,Yiran Ye,Wolfgang Tress,Liming Ding,Michael Grätzel,Chenyi Yi +12 more
TL;DR: In this paper , vacuum evaporation of lead iodide and solution processing of organic ammonium halide is combined to produce large-area homogeneous perovskite films with large grains in a highly reproducible way.
Journal ArticleDOI
Studies of alkylphenothiazinesulphonate micellar assemblies in aqueous solution
TL;DR: In this article, the micellar properties and photochemical behaviour of sodium 9-alkylphenothiazinesulphonate and sodium ω-carbozol-9-ylalkanesulphinate (where alkyl = C10H21 and C12H25) have been examined for the fundamental study of photoionization in mousellar assemblies.
