Optical properties of thePb2+-based aggregated phase in a CsCl host crystal: Quantum-confinement effects

The spectral luminescence characteristicsof RbPbCl3 : Cs crystals in the 4–20 eV region

“…The reliability of the obtained decay time constant τ f1 of CsPbCl 3 microcrystals dispersed in the RbPbCl 3 matrix is indirectly confirmed by the results obtained for the luminescence decay kinetics of CsPbCl 3 nanocrystals dispersed in a CsCl matrix. The decay time constant of CsPbCl 3 nanocrystals amounts to 30-40 ps under excitation by a picosecond dye laser with an exiting pulse of a few picoseconds in duration [4].…”

“…The luminescence intensity of such nanocrystals is comparable with that of CsPbCl 3 single crystals. CsPbCl 3 -like nanocrystals may be obtained in CsCl : Pb (C Pb = 0.05-1 mol%) [4][5][6], PbCl 2 :Cs (C Cs = 0.5-1 mol%) [7] or CsBCl 3 : Pb (B = Ca, Sr, Mg; C Pb = 0.5-1 mol%) [8] as a result of prolonged (t = 10-100 h) high-temperature (T = 180-220 °C) annealing. The basic mechanism of such nanocrystal formation is explained by the thermally activated motion of anion and cation vacancies and by the tendency of Pb…”

Luminescence properties of Sn-containing microcrystals in CsBr:Sn crystal

“…Studies for luminescent-kinetic parameters of semiconducting nano-and microcrystals embedded in different insulator matrices represent one of possible ways for searching the materials of different functional use [1]. The appropriate example of those materials is nano-and microcrystals based on mercury-like ions (Pb 2+ , Sn 2+ , Bi 3+ and Sb 3+ ), which are promising for applications as fast scintillators [2] and active media of thin-film solid state lasers [3].…”

Luminescent Kinetic Characteristics of Cspbcl_3 Aggregates Dispersed in Rb_{1-X}cs_{x}cl (X=0.05-0.2) Matrices

“…Some of them are characterized by a high intensity of luminescence with short decay times (tens of picoseconds) [1]. Such luminescent parameters make these materials prospective for the development of fast detectors of high-energy irradiation.…”

“…The formation of nanocrystals has been confirmed by manifestation of the quantum size effect in their spectral luminescent characteristics [1][2][3][4]. High efficiency of the luminescent method of identifying the crystal type and nanocrystal sizes in the dielectric matrix has been analyzed in [5].…”
