Title: Photoluminescence fatigue and inhomogeneous line broadening in semi-insulating Tl₆ SeI₄ single crystals

Abstract

Photoluminescence (PL) properties of semi-insulating Tl₆SeI₄ have been investigated. A broad emission band centered at 1.63 ± 0.02 eV was observed in all samples. The PL emission band is excitonic in nature and is tentatively attributed to a bound exciton emission. PL fatigue (a reduction in PL intensity under prolonged laser excitation) was always observed. The amount of PL fatigue depended on excitation power and temperature. PL fatigue kinetics are described by a stretched exponential with nominal lifetimes in the 10–265 s range. The recovery of the PL occurred within a few seconds of light cessation. The magnitude of PL fatigue in different samples correlated with inhomogeneous line broadening of the 1.63 eV emission band, such that broader bands exhibited more fatigue. An additional luminescence band centered at 1.78 eV was observed which increased in intensity under prolonged laser irradiation. The fatigue phenomenon is tentatively attributed to two mechanisms—the formation of photo-induced defects and the formation of quasi-stable particles. Both of these mechanisms introduce additional radiative and non-radiative recombination channels that lead to a decrease in the PL intensity under prolonged laser irradiation. Finally, since inhomogeneous line broadening and PL fatigue are related to the concentration of defects or impurities,more »« less

Strong Electron–Phonon Coupling and Self-Trapped Excitons in the Defect Halide Perovskites A₃M₂I₉ (A = Cs, Rb; M = Bi, Sb)

Journal Article McCall, Kyle M. ; Stoumpos, Constantinos C. ; Kostina, Svetlana S. ; ... - Chemistry of Materials

The optical and electronic properties of Bridgman grown single crystals of the wide-bandgap semiconducting defect halide perovskites A₃M₂I₉ (A = Cs, Rb; M = Bi, Sb) have been investigated. Intense Raman scattering was observed at room temperature for each compound, indicating high polarizability and strong electron–phonon coupling. Both low-temperature and room-temperature photoluminescence (PL) were measured for each compound. Cs₃Sb₂I₉ and Rb₃Sb₂I₉ have broad PL emission bands between 1.75 and 2.05 eV with peaks at 1.96 and 1.92 eV, respectively. The Cs₃Bi₂I₉ PL spectra showed broad emission consisting of several overlapping bands in the 1.65–2.2 eV range. Evidence of strong electron–phononmore »« less

TlSn₂I₅, a Robust Halide Antiperovskite Semiconductor for γ-Ray Detection at Room Temperature

Journal Article Lin, Wenwen ; Stoumpos, Constantinos C. ; Liu, Zhifu ; ... - ACS Photonics

The semiconductor TlSn₂I₅ with a two-dimensional crystal structure and an antiperovskite topology is a promising novel detection material. The compound crystallizes in the I4/mcm space group, has an indirect band gap of 2.14 eV, and melts congruently at 314 °C. Electronic band structure calculations reveal that the most facile electron transport is along the ab layered plane. Compared to CH₃NH₃PbX₃ (X = Br, I), TlSn₂I₅ features higher long-term stability, higher photon stopping power (average atomic number of 55), higher resistivity (~10¹⁰ Ω·cm), and robust mechanical properties. Centimeter-size TlSn₂I₅ single crystals grown from the melt by the Bridgman method can bemore »« less

Role of oxygen vacancies on light emission mechanisms in SrTiO₃ induced by high-energy particles

Journal Article Crespillo, M. L. ; Graham, J. T. ; Agulló-López, F. ; ... - Journal of Physics. D, Applied Physics

Light emission under MeV hydrogen and oxygen ions in stoichiometric SrTiO₃ are identified at temperatures of 100 K, 170 K and room-temperature. MeV ions predominately deposit their energies to electrons in SrTiO₃ with energy densities orders of magnitude higher than from UV or x-ray sources but comparable to femtosecond lasers. The ionoluminescence (IL) spectra can be resolved into three main Gaussian bands at 2.0 eV, 2.5 eV and 2.8 eV, whose relative contributions strongly depend on irradiation temperature, electronic energy loss and irradiation fluence. Two main bands, observed at 2.5 eV and 2.8 eV, are intrinsic and associated with electron–holemore »« less

Ultra-wide bandgap β-Ga₂O₃ films: Optical, phonon, and temperature response properties

Journal Article Thapa, Dinesh ; Lapp, Jeffrey ; Lukman, Isiaka ; ... - AIP Advances

Optical and phonon interactions of Ga₂O₃ thin films with nanocrystalline morphology were studied at extreme temperatures. The films were grown using a sputtering technique and analyzed via temperature response transmission, Raman scattering, and high-resolution deep-UV photoluminescence (PL). Raman modes indicated that the structure corresponds to the β-phase. The optical-gap at the range of 77–620 K exhibited a redshift of ~200 meV, with a temperature coefficient of ~0.4 meV/K. The optical-gap at room-temperature is 4.85 eV. The electron–phonon interaction model at that temperature range pointed to a low energy phonon, ~31 meV, that is involved in the thermal properties of themore »« less
