Synthesis and luminescence of red MEH-PPV: P3OT polymer

This paper investigates the synthesis processes for poly(3-octylthiophene) (P3OT) and poly[2-methoxy-5-(2 0-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). The proton nuclear magnetic resonance (H NMR) and the Fourier transform infrared spectrophotometer (FTIR) were used to identify the chemical structure and functional group of synthesized polymers, respectively. The efficient Förster energy ...

Red luminescence in calix[4]arene-europium hybrid material

Inorganic-organic hybrid material based on Eu and calix[4]arene bearing four carboxylic acid groups has been synthesized via hydro(solvo)thermal method assisted by microwave irradiation. The obtained sample was characterized by FT-IR, PXRD, SEM and photoluminescence. The results showed the formation of coordination polymer with low symmetry around Eu ion. The monoexponential luminescence decay ...

Luminescence Properties of Epitaxially Grown GaN and InGaN Layers Around ZnO Nanopillars

GaN and InGaN layers grown around ZnO nanopillars by metalorganic vapor phase epitaxy (MOVPE) are investigated by means of photoluminescence (PL) and locally resolved cathodoluminescence (CL). A multi layer growth process involving deposition at different growth conditions in a step-wise manner has been employed for the coaxially grown GaN. Then InGaN/GaN quantum wells and barriers have been de...
