| Popis | Laser ablation synthesis of nano-tellurium and tellurium clusters Tem (m = 1, 6) from bulk tellurium was developed. For a generation of tellurium nanoparticles in liquids (e.g. ethanol) Nd: YAG laser at 1064 nm was used while for the clusters synthesis the Nd: YAG laser at 355 nm on a commercial mass spectrometer was applied. Mass spectrometric characterization of synthesized product using Matrix Assisted Laser Desorption Ionization Time of Flight (MALDI-TOF) was done. It was found that nano-tellurium produced in ethanol rapidly aggregates and precipitate. The aggregation can be stopped (or diminished) via cooling to low temperature (approx. 5 °C) or complexing Te nanoparticles in a ß-cyclodextrin forming supramolecular complex. |
