Özet:

 

The structural and optical properties of the AuBr nanocrystals embedded in the KBr single crystals grown  by the Czochralski method were studied using several techniques. The X-ray diffraction reveals their formation and  incorporation. The crystallite average radii calculated from XRD using the Scherrer's formula was found to vary between  19 and 39 nm. The photoluminescence spectra obtained on these same samples present an emission band located at 1.91  eV (650 nm), which can be attributed to the orange luminescence of AuBr nanocrystals. However, the photoluminescence  excitation measurements of these nanocrystals exhibit an excitation band located at 3.44 eV (360 nm), slightly shifted  towards higher energies in comparison with the massive crystal.
