Optoelectronic application of perovskite nanoparticles
Ambro, Filip ; Zdražil,, Lukáš (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with the utilization of perovskite nanoparticles in optoelectronics. The thesis is composed of three main parts. The first part focuses on the theoretical properties of perovskite materials, with an emphasis on their structure and properties influencing their electrical and optical behavior. The second part describes the procedure for preparing solutions of these nanoparticles, their subsequent characterization, the preparation of thin layers, and the subsequent characterization of the optical, electrical, and dielectric properties of these layers. The final part is dedicated to presenting the results of the work and discussion.

Study of leaded and lead-free perovskite nanoparticles properties
Holečková, Jana ; Zdražil, Lukáš (referee) ; Zmeškal, Oldřich (advisor)
This master thesis examines optical properties of lead and lead-free perovskite nanoparticles. Two types of perovskite nanoparticle solutions with lead or bismuth were prepared. One type was hybrid inorganic-organic perovskite nanoparticles, either containing bromine anions or chlorine anions. The second type was purely inorganic perovskite nanoparticles, also containing either bromine anions or chlorine anions. During synthesis were used different solvents. Solutions were characterized by dynamic light scattering, fluorescence spektrometry and UV-VIS spectrophotometry. The measured results were discussed.
