We have fabricated semiconducting polymer nanoparticles from poly[2-methoxy-5-(2'-ethyl-hexyloxy)-p-phenylene vinylene] (MEH-PPV), poly(N-vinylcarbazole) (PVK), and their blends via a reprecipitation method. When excited by the peak wavelength of the

We report the temperature-dependent photoluminescence (PL) behavior of two poly (p-phenylene-vinylene) derivatives with different backbones, a homopolymer poly-[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene-vinylene] (MEH-PPV) and a copolymer poly-

We report the photoluminescence characteristics of solid solutions of poly[2-methox-5-(2′-ethyl-hexyloxy)-p-phenylene vinylene] (MEH-PPV) with different concentrations in polystyrene. Reduction in the distances between the MEH-PPV chains with incre

With anodic alumina with an ordered nanopore array used as a template, poly[2-metoxy-5-(2′-ethyl-hexyloxy)-p-phenylene vinylene] (MEH–PPV) was embedded into the nanopores, and then two-dimensional arrays of light-emitting nanopolymers were prepar

The photoluminescence (PL) spectra of poly(2,5-bis-(tri-ethoxy)-1,4-phenylene vinylene) (BTEO- PPV) films are blue-shifted with increasing thermal anneal- ing temperature. It is known from the UV-vis absorption spectra that thermal annealing decrease

Ge-doped SiO 2 films were deposited on p -Si substrates by magnetron sputtering and metal–insulator–semiconductor (MIS) structures were fabricated with semitransparent Au layers on SiO 2 films. The MIS structures exhibit electroluminescence (EL)

We present the electrical and optical characteristics of a single-ion transport light-emitting electrochemical cell (SLEC) based on poly(p-phenylene vinylene) (PPV) derivative containing aryl-substituted oxadiazole in the backbone (MEH-OPPV). Ionized

The frequency dependent capacitance of semiconductor-electrolyte junction and its relationship to the surface roughness of the semiconductor and the ions in the electrolyte are discussed. Due to very low mobility of the ions, the observed capacitance
