PhD. studies

Doctoral study programmes at the UCT Prague are carried out in a full-time form or a combination of full-time and distance learning, always on the basis of an individually scheduled study plan and checking study duties. The standard lenght of a doctoral study programme is four years according to current accreditation of the study program.

The University accepts PhD students on a rolling basis throughout the calendar year; it is essential when making your application for doctoral studies that you find an advisor who will guide you through the entire period of your PhD studies. 


Available dissertation themes in the Laboratory of Inorganic Materials

  • Heavy metal oxide glasses

Supervisor: Doc. Ing. Jaroslav Kloužek, CSc.
Supervisor specialist: Ing. Petr Kostka, Ph.D.
The glass network of heavy metal oxide glasses is formed by oxides such as TeO2, GeO2 or Sb2O3 instead of SiO2. These glasses stand out in comparison with conventional glasses particularly by wide interval of transparency ranging up to much longer wavelengths, lower phonon energies, higher refractive index, outstanding nonlinear properties, high solubility of rare-earth ions accompanied by high quantum yield of radiative transition etc. The work will focus on the preparation and characterization of new materials – glasses – containing antimony and/or bismuth oxides. Characterization of the prepared materials will include their basic properties such as density, molar volume, thermal stability, chemical resistance, hardness, optical transmission, refractive index, etc. Correlation between structural units forming the glass network and the resulting properties will be investigated and the influence of processing conditions during glass preparation on these properties will be evaluated.


  • Chalcogenide glasses and optical fibres

Supervisor: Doc. Ing. Jaroslav Kloužek, CSc.
Supervisor specialist: Ing. Petr Kostka, Ph.D.
Glass network of chalcogenide glasses is formed by S, Se or Te in combination with metals and/or semimetals. The presence of oxygen in these materials is usually undesirable. Real applications of this type of glass are conditioned mainly by high purity of the prepared or manufactured materials. Procedures for preparing high-purity chalcogenide glasses allowing for their use in fiber optics, already exist. The work will include the preparation of chalcogenide glasses, optimization of their composition, dotation of materials by rare earth ions and examination of the relationship between the vitreous matrix and the dopant. It is also possible to focus some of the efforts on new technological procedures for further material purification. The subsequent step will be to prepare preforms for optical fibres drawing, including the processing of structured preforms for drawing optical microstructured fibres (photonic crystal fibres) and characterization of prepared fibres.
