Noncontact temperature measurements using luminescent materials
Jedlička, Jindřich ; Nebojsa, Alois (referee) ; Ligmajer, Filip (advisor)
This diploma thesis deals with noncontact temperature measurement using luminescent materials. In the theoretical part of the thesis, luminescent materials were selected on the basis of a literature review with respect to sensitivity and operating temperature range. In the experimental part of the thesis, photoluminescence of CdSe/ZnS and GaAs quantum dots for various temperatures was measured and the relative change of luminescence parameters such as emission peak position, intensity, intensity ratio of two emission peaks, and lifetime of luminescence were determined from the measurements in agreement with expectations according to the literature. Achieving high spatial resolution would be made possible by measuring cathodoluminescence, where the luminescence spectra are obtained with an order of magnitude higher spatial resolution. These measurements and the influence of electron beam on the luminescence quality of selected materials will be subject of further experimental study.
Preparation of GeSn nanostructures
Jedlička, Jindřich ; Voborný, Stanislav (referee) ; Kolíbal, Miroslav (advisor)
This bachelor thesis deals with the methods of preparation of GeSn nanowires. In the theoretical part of the thesis the band structure of solid states is described and the interesting properties of GeSn material are mentioned. The growth mechanism of nanowires and methods of preparation of GeSn nanowires are introduced. In the experimental part of the thesis the effusion cell for Sn deposition was assembled and the testing and calibration were performed.
