Effect of Yb doping on the optical and photoelectric properties of CsPbCl3 single crystals
In this paper, the effect of Yb dopant on the optical and photoelectric properties of CsPbCl3:Yb single crystals is studied. The position of the main energy level of Yb3+ ions relative to the energy band was determined. Two channels of electron photoionization into the conduction band were identified, which are photo-stimulated transition of valence electrons and transition of electrons from the ground level of the Yb3+ dopant ion. The crucial role of Yb2+ ions in the manifestation of the quantum cutting effect was shown. A non-uniform distribution of ytterbium dopant in the CsPbCl3:Yb single crystal volume was revealed. It was established that the absolute quantum yield of ytterbium luminescence in CsPbCl3:Yb single crystals in the near-infrared region at Yb concentration of 2 mol.% reaches 86%.
