Electric-field-induced quenching of photoluminescence in photoconductive organic thin film structures based on Eu3+ complexes
PublicationW pracy badano elektrycznopolowe wygaszenie fotoluminescencji w organicznych kompleksach europu Eu(III) rozdyspergowanych w matrycy poliwęglan: dwuamina TPD. W układzie z elektrodami Al/Al obserwowano wygaszenie fotoluminescencji wywołane dysocjacją ekscytonów. W układzie z elektrodami ITO(+)/Au(-) oprócz dysocjacji ekscytonów obserwowano również silne wygaszenie ekscytonów na ładunku elektrycznym wstrzykniętym do próbki. Analiza...

Electro-photoluminescence in organics
PublicationElektro-fotoluminescencję zaobserwowano w układzie ITO(+)/emiter/Ca(-), gdzie emiter wzbudzany światłem UV (350nm) zawierał dendrymer aminowy m-MTDATA, pochodną fenantroliny BPT i organiczny kompleks platyny PtL2Cl. Widmo fotoluminescencji pochodzi od singletowych ekscypleksów m-MTDATA:BPT i trypletowych ekscypleksów m-MTDATA:PtL2Cl. Ze wzrostem pola elektrycznego następuje wygaszanie ekscypleksów na skutek ich dysocjacji na nośniki...

Removal of phenolic inhibitor compounds from hydrolysates and post-fermentation broths by using a Hydrophobic Magnetic Deep Eutectic Solvent
PublicationHydroxymethylfurfural (HMF), furfural (FF), hydroquinone (HQ), and vanillin (VAN) are among the main inhibitors generated during most of biomass pre-treatments prior to fermentation processes. They are recognized as toxic to several fermentative microorganisms and therefore cause a decrease in biohydrogen or biofuel production (after hydrolysis). Moreover, if they are released into aqueous solutions (after fermentation), they can...

Magnetic field effects on emission and current in Alq3 - based electroluminescent devices.
PublicationW pracy zaobserwowano stromy wzrost natężenia elektroluminescencji w polach magnetycznych nie przekraczających 300mT. Efekt ten wywołany jest magnetyczno polową redukcją stopnia zmieszania singletowych i trypletowych par elektron dziura, wymuszonego przez nadsubtelne oddziaływanie spinów elektronowych z ich otoczeniem jądrowym.

Magetic field effects on organic electrophosphorescence.
PublicationPo raz pierwszy zarejestrowano kilkuprocentowy wzrost kwantowej wydajności elektroluminescencji (EL) w diodach z emiterami fosforescencyjnymi Ir(ppy)3 i PtOEP umieszczonymi w zewnętrznym polu magnetycznym. Zaobserwowane zmiany wyjaśniono na podstawie magnetycznej modulacji oddziaływań nadsubtelnych powodujących wzajemną konwersję singletowych i trypletowych skorelowanych par elektron-dziura (e-h).

Collective filter evaluation of an FSD filter-based resampling algorithm. [online] W: Online Symposium for Electronics Engineers. Techonline Bedford, Massachusetts, USA. [Dostęp: 15 stycznia**2002]. Dostępny w World Wide Web: http://www.techonline.com/community/ed_resource/feature_article/14917/[6 s. 5 rys.] Badanie algorytmu zmiany szybkości próbkowania realizowanego w oparciu o filtry FSD za pośrednictwem analizy filtru zbiorczego.
PublicationW pracy przedstawiono koncepcję filtru zbiorczego dla potrzeb oceny jakościalgorytmu zmiany szybkości próbkowania realizowanego w oparciu o filtry u-łamkowo-opóźniające (FSD). W przypadku takiego algorytmu przepróbkowania dowyznaczania każdej próbki wyjściowej potrzebny jest filtr FSD o innm opóź-nieniu ułamkowym. Z kolei jakość takiego filtru zależy właśnie od jego opóź-nienia, co stwarza problemy w ocenie jakości samego...
