Cíle předmětu
This interdisciplinary short course is an intensive introduction to the properties and usage of light emitting diodes (LEDs) in chemical analysis and chemistry in general. The course will cover the background and theory and then will focus on practical issues and the applications of LEDs particularly for analytical optical methods (photometry, fluorimetry), optical detection in analytical flow-through methods (FIA, HPLC, CE), optical sensors, microfluidic chips, fluorescence microscopy and visualization in photochemistry and teaching. Examples of some elementary techniques used to characterise LEDs including measurement of emission spectra will be conducted as hands-on experiments. This is a both beginners and intermediate level course with respect to LEDs. The course is designed in such a way that a wide range of participants can benefit: those curious about the use of LEDs in chemistry and science, those starting to use LEDs, having some experience, and students, scientists, engineers or lecturers considering whether LEDs could be used in their specific work. The course is also suitable for persons involved in teaching in the areas of instrumental analytical chemistry, physical chemistry and photochemistry. The participants will benefit from some background in chemistry and analytical chemistry in particular, but this interdisciplinary course is designed in such a way that students or professionals with other background can participate and benefit as well. Prior exposure to and use of other LEDs is useful but not expected or necessary.
