Rezumat | ||||||
In this work are studied photoluminescence (PL) spectra from GaS crystals and GaS crystals intercalated with Zn and Cd atoms. Metal atoms were intercalated by 6 hours heat tratament at the temperature of 750 K in metal vapor atmosphere. Gallium dots are created on external surface and between S-Ga-Ga-S packages. This dots are aranged as distorted hexagons. Zn intercalation leads to formation of two PL bands with maximum at 2.12 eV and 2.84 eV, energyes. PL spectra of Cd intercalated crystals containes one simple contour band at 293 K, and two bands at 78 K. Band with maximum at 2.424 eV has a complex structure, composed by fononic repeats of indirect excitons emission. |
