Using of Perovskite Nanoparticles in Biochemistry
Srncová, Melanie ; Tumová, Šárka (referee) ; Pospíšil, Jan (advisor)
This bachelor's thesis examines study of the properties of lead halide perovskite nanoparticles and their use in biochemistry. The synthesis of two types of perovskite nanoparticles MAPbBr3 and MAPbCl3 was performed using the LARP method. During the synthesis was observed the influence of the mixing length of the precursors on the properties of these solutions, which were characterized using UV-VIS spectrophotometry, fluorescence spectrometry and dynamic light scattering. A discussion of the obtained results was carried out along with a discussion of the suitability of using these perovskite nanoparticles in biochemistry due to the toxicity of the lead that these nanoparticles contain.
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.
