Photoluminescence study of light-induced modifications of (electro)chemically prepared polypyrrole
Galář, P. ; Malý, P. ; Čermák, Jan ; Rezek, Bohuslav ; Kromka, Alexander
Permanent modification of polypyrrole (Ppy) after UV light irradiation were studied by photoluminiscence (PL), optical absorption and X-ray photoelectron spectroscopy (XPS). Ppy samples were prepared by electrochemical anodic oxidation and chemical oxidation. Influence of light exposure on polymer properties was studied under ambient condition, low pressure and after polymer annealing from 300K to 520K.
Electrochemical growth of polypyrrole on boron doped diamonds
Ukraintsev, Egor ; Kromka, Alexander ; Haenen, K. ; Rezek, Bohuslav
To find out the mechanism of the electrochemical attachment of polypyrrole (Ppy) to diamond we grow Ppy layers on hydrogen and oxygen terminated boron doped diamond surfaces (BDD) using constant current applied between the BDD and the platinum wire.
Synthesis, structure, and opto-electronic properties of organic dies on diamond
Rezek, Bohuslav ; Čermák, Jan ; Ukraintsev, Egor ; Hubík, Pavel ; Mareš, Jiří J. ; Ledinský, Martin ; Fejfar, Antonín ; Kočka, Jan ; Kromka, Alexander
We prepare a thin-film heterojunction of polypyrrole (Ppy) on hydrogen-terminated diamond by electro-polymerization from solution. We combine advanced scanning techniques (AFM, KFM, micro-Raman) to characterize microscopic structural, chemical, and opto-electronic properties of such system.
Plošný přenos náboje na rozhraní polypyrol-diamant
Čermák, Jan ; Rezek, Bohuslav ; Hubík, Pavel ; Mareš, Jiří J. ; Kromka, Alexander ; Fejfar, Antonín
In this study we examine in-plane hole transport in polypyrrole-diamond interface.
