Description
  • V široké teplotní (12 – 300 K) a spektrální (300 – 1200 nm) oblasti byla studována emisní spektra fotoluminiscence krystalů KTaO3:Er s cílem odhalit luminiscenční centra spojená s ionty Er a objasnit jejich optické vlastnosti. Při buzení světlem s energií fotonů větší než je šířka zakázaného pásu byl u krystalů KTaO3:Er pozorován při nízkých teplotách široký asymetrický emisní pás s maximem v blízkosti 490 nm při 12 K, který odpovídá dobře známé “zelené fotoluminiscenci krystalů KTaO3. Dopování erbiem bylo doprovázeno objevením se úzkých strukturovaných emisních pásů v okolí 550, 660, and 850 nm, které byly přisouzeny zářivým přechodům v Er3+ iontech s 4f11 elektronovou konfigurací.

  • Photoluminescence emission spectra of KTaO3:Er crystals was studied within the wide temperature (12 – 300 K) and spectral (300 – 1200 nm) regions in order to reveal luminescence centers related to Er ions and to elucidate their optical properties. Under excitation with band-gap light at low temperatures, the KTaO3:Er crystals shoved a broad asymmetric emission band peaking near 490 nm at 12 K that belongs to well-known “green photoluminescence of KTaO3 crystals. Erbium doping was accompanied by appearance of narrow structured emission bands in the vicinity of 550, 660, and 850 nm that were attributed to radiative transitions within Er3+ ions with 4f11 electron configuration.
