Luminescence sensitivity changes in natural quartz induced by high temperature annealing: a high frequency EPR and OSL study
Poolton, NRJ; SMITH, GM; RIEDI, PC; Bulur, Enver; Botter-Jensen, L; MURRAY, AS; ADRIAN, M (2000-04-21)
Quartz undergoes very significant luminescence sensitivity changes after high temperature annealing (0-1200 degrees C), with particular enhancement occurring between the phase transition temperatures 573 and 870 degrees C. In order to understand why this occurs, high frequency electron paramagnetic resonance (EPR), operating at 90 GHz, has been used to monitor the structure and population of defects in natural sedimentary quartz, following annealing and gamma-irradiation. The results are compared with the o...
Luminescence from silicon nanoparticles in SiO2: atomic force microscopy and transmission electron microscopy studies
Mayandi, J.; Finstad, T. G.; Foss, S.; Thogersen, A.; Serincan, U.; Turan, Raşit (IOP Publishing, 2006-09-01)
Si nanocrystals in thermal oxide films ( similar to 250 nm) were fabricated by 100 keV Si ion implantation at various doses followed by high temperature annealing. After annealing a sample implanted with a dose of 1 x 10(17) cm(-2) at 1050 degrees C for 2 h, a broad photoluminescence peak centred around 880 nm was observed. A dose of 5 x 10(16) cm(-2) yields a considerable blue shift of about 100 nm relative to the higher dose. Transmission electron microscopy and atomic force microscopy (AFM) are used to c...
Luminescence of molecular and block copolymeric 2,7-bis(phenylethenyl)- fluorenones; identifying green-band emitter sites in a fluorene-based luminophore
RATHNAYAKE, Hemali P.; Çırpan, Ali; KARASZ, Frank E.; ODOI, Michael Y.; HAMMER, Nathan I.; BARNES, Michael D.; LAHTI, Paul M. (American Chemical Society (ACS), 2007-06-26)
2,7-Bis(3,4,5-trimethoxyphenylethenyl)fluorenone (OFOPV) and a segmented oligomer analogue linking OFOPV units with polymethylene flexible spacersalt-poly(2,6-dimethoxylphenylene-4-vinylene-[9-fluorenone-2-yl-7-vinylene]3,5-dimethoxyphenylene-4-[1,6-hexanedioxyl]) (pFOPV)were synthesized and their luminescence properties studied. Solution-phase photoluminescence (PL) of OFOPV and pFOPV shows concentration-dependent relative intensities of a fine-structured higher energy band and a featureless lower energy b...
Luminescence of fluorenes 2,7-conjugatively extended with pyrenylvinylene and pyrenylvinylene-phenylenevinylene
Çırpan, Ali; LAHTI, Paul M.; KARASZ, Frank E. (Royal Society of Chemistry (RSC), 2007-01-01)
2,7-Bis(1'-pyrenylvinylene)-9,9-diethylfluorene (1) and 2,7-bis(1'-pyrenylvinylene- 4 ''-phenylenevinylene)-9,9-diethylfluorene (2) were synthesized and their static luminescence behavior assessed. They show solution photoluminescence (PL) maxima in chloroform at 475 nm and 467 nm, with quantum efficiencies of 54% and 52%, respectively. Double-layer LED devices with configuration ITO/PEDOT-PSS/(1 or 2)/Ca-Al emitted blue-green light with turn-on voltages of 2.5 V and emission maxima at 500 nm (2.48 eV); the...
