WarCraft III - Tyry noob'ów
Streszczenie
W ramach pracy zostały zawarte badania nad kropkami kwantowymi CdSe/ZnS w roz-tworze organicznym oraz nad cienką warstwą Langmuira-Blodgett tych kropek na podłożu stałym.
Zarejestrowane zostały izotermy zależności ciśnienia powierzchniowego od średniej powierzchni przypadającej na jedną molekułę dla określonej ilości nakroplonych kropek na powierzchnię fazy nośnej oraz wytworzona została pojedyncza warstwa na szkle borowo-krzemowym i na złocie. Zmierzone zostały podstawowe właściwości spektroskopowe, przy wykorzystaniu spektroskopii absorpcyjnej oraz fluorescencyjnej dla zakresu światła UV-Vis oraz wyznaczone zostały średnie czasy życia fluorescencji, zarówno dla sporządzonego roz-tworu jak i wytworzonych warstw LB.
W ramach części inżynierskiej zaprojektowany został projekt przystawki do pomiarów czasów życia fluorescencji z warstw Langmuira-Blodgett dla fluorymetru PTI.
Abstract
In the paper has been included research on quantum dots CdSe/ZnS in the organic so-lution and in the thin layer Langmuir-Blodgett films of these dots on the solid substratum.
Isotherms were recorded dependence of the surface pressure from average surface for one molecule for a specified number of carried dots on the surface phase carrier, and was created a single layer on glass boron-silicon and on gold. Measured were the fundamental spectroscopic properties, using absorption spectroscopy and fluorescence for a range of UV-Vis and have been determined average fluorescence lifetimes for both, the prepared solution and LB films created.
As part of an engineering, was design project a holder to measure the fluorescence lifetimes of the Langmuir-Blodgett films to fluorometer PTI.

Abstract
In the paper has been included research on quantum dots CdSe/ZnS in the organic solution and in the thin layer Langmuir-Blodgett films of these dots on the solid substratum.
Isotherms were recorded in dependence of the surface pressure upon average surface per one molecule for a specified number of carried dots on the surface phase carrier, and there was created a single layer on boron-silicon glass and on gold. The fundamental spectroscopic properties were measured by using absorption and fluorescence for a range of UV-Vis spectroscopy and have been determined the average fluorescence lifetimes for both, the prepared solution and created LB films.
As part of an engineering, there was design a holder to measure the fluorescence lifetimes of the Langmuir-Blodgett films to fluorometer PTI.

Abstract
In the paper has been included the results of research on quantum dots CdSe/ZnS in the organic so-lution and in the thin layer Langmuir-Blodgett films on a solid substrat.
Isotherms were recorded in dependence of the surface pressure upon surface mini-trough for a specified number of carried dots on the surface phase carrier. Also there was created a single layer on quartz glass and on gold. The fundamental spectroscopic properties were determined by using absorption and fluorescence for a range of UV-VIS spectroscopy and the average fluorescence lifetimes for both, the prepared solution and created LB films have been also determined.
As a engineering part, there a holder for measurement of fluorescence lifetimes of the Langmuir-Blodgett films for a fluorometer PTI was design.
A tak być powinno i jest i będzie !
