Spectral redistribution of waveguided emission in BEH-PPV films
(Taylor & Francis Ltd, 2002-01-01)
We report on spectral redistribution of the photoluminescence (PL) emission from the edge of thin-film planar waveguides of the conjugated polymer BEH-PPV [Poly(2,5-bis(2'-ethyl-hexyl)-1,4-phenylenevinylene] induced by ...

Tracking high molecular weight polymer interdiffusion on a SERS-based platform
(John Wiley & Sons Ltd, 2016-11-18)
We describe the implementation of an experimental setup based on Surface Enhanced Raman Spectroscopy (SERS) to investigate polymer interdiffusion. Ultra-thin bilayer films of deuterated polystyrene (dPS) and polystyrene ...
Molecular organization relationship of low-bandgap polymers at the air-water interface and in solid films
(2018-10-15)
Low-bandgap organic polymers, poly[(4,4‑bis(2‑ethylhexyl)cyclopenta‑[2,1‑b:3,4‑b′]dithiophene)2,6‑diyl‑al‑(2,1,3‑benzothiadiazole)‑4,7‑diyl](PCPDTBT), and poly [(4,4′‑dioctyldithieno[3,2‑b:2′,3′d]silol‑2,6‑diyl)‑alt‑(2,1 ...
Thioxanthone Sensitized Photodegradation of Poly(alkyl methacrylate) Films
(JOHN WILEY & SONS INC, 2010)
The thioxanthone-sensitized photodegradation of poly(alkyl methacrylate) films [alkyl = methyl, ethyl, butyl, and hexyl] was studied using near UV-vis light. The photooxidation process continued even after the total ...
Structural properties of buried conducting layers formed by very low energy ion implantation of gold into polymer
(AMER INST PHYSICS, 2009)
We have investigated the fundamental structural properties of conducting thin films formed by implanting gold ions into polymethylmethacrylate (PMMA) polymer at 49 eV using a repetitively pulsed cathodic arc plasma gun. ...
