| Description
| - Elektrodepozice polypyrrolového filmu na porézní křemíkový povrch umožnila zlepšení jeho fotoluminiscenčních vlastností pro detekci plynů. Fotoluminiscenční zhášení odezvy senzoru bylo měřeno pro vodu a homologickou řadu lineárních alkoholů v plynné fázi. Koncentrační závislost fotoluminiscenčního zhášení polypyrrolem modifikovaných vzorků pro vodu a methanol vykazovala Stern-Volmer chování, doba trvání fotoluminiscence senzoru na koncentraci analytu doprovázená zhášením fotoluminiscence při vysokých koncentracích byla pozorována pro C2-C6 lineární alkoholy. Interval fotoluminiscence polypyrrolem modifikovaných vzorků klesal s délkou řetězce alkoholu. Výrazný pokles odezvy fotoluminiscence senzoru k nižším alkoholům byl připisován jejich silné interakci s polypyrrolovým povrchem a potlačení průniku analytu do porézní matrice. Operační stabilita polypyrrolem modifikovaného porézního křemíku byla zlepšena v porovnání se samotným porézním křemíkem. (cs)
- Electrodeposition of polypyrrole film on porous silicon surface was used to improve its photoluminescence properties for sensing of chemical species in gas phase. Photoluminescence quenching sensor response was measured for water and a homological set of linear alcohols in gas phase. We observed modified photoluminescence quenching response from polypyrrole-modified porous silicon as compared with as-prepared porous silicon. For as-prepared porous silicon samples, the dependence of photoluminescence quenching on analyte concentration revealed Stern-Volmer behavior. Concentration dependence of photoluminescence quenching response of polypyrrole-modified samples for water and methanol exhibited Stern-Volmer behavior as well, for C2-C6 linear alcohols a period of photoluminescence enhancement on the concentration dependence onset followed by photoluminescence quenching at higher concentrations was observed. The interval of photoluminescence enhancement response from polypyrrole-modified samples was conti
