TAILIEUCHUNG - Excitonic states and structural stability in two-dimensional hybrid organic-inorganic perovskites

Two-dimensional (2D) perovskites are a new class of functional materials that may find applications in various technologically important areas. Due to the better moisture and illumination stability, layered perovskites can be the next generation of materials for solar light-harvesting applications, as well as for light emitting diodes (LEDs). | Journal of Science Advanced Materials and Devices 4 2019 189e200 Contents lists available at ScienceDirect Journal of Science Advanced Materials and Devices journal homepage locate jsamd Review Article Excitonic states and structural stability in two-dimensional hybrid organic-inorganic perovskites Yulia Lekina Ze Xiang Shen Division of Physics and Applied Physics School of Physical and Mathematical Sciences Nanyang Technological University SPMS-04-01 21 Nanyang Link 637371 Singapore a r t i c l e i n f o a b s t r a c t Article history Two-dimensional 2D perovskites are a new class of functional materials that may find applications in Received 26 March 2019 various technologically important areas. Due to the better moisture and illumination stability layered Accepted 27 March 2019 perovskites can be the next generation of materials for solar light-harvesting applications as well as for Available online 3 April 2019 light emitting diodes LEDs . Besides extended chemical engineering possibilities allow obtaining advanced perovskite materials with desirable functional properties such as tunable band gap strong Keywords exciton-phonon coupling white light emission spin-related effects etc. A full understanding of the Two-dimensional perovskites fundamental properties is essential for developing new 2D perovskite-based technologies. In this paper Layered perovskites Excitons recent reports on 2D perovskites are reviewed including the synthesis methods of single crystals Excitonic states nanosheets and films the crystal and electronic structures the excitonic states and interactions the High pressure properties of the materials under low temperature and high pressure and a brief discussion on the Photoluminescence challenges in understanding the fundamental properties of the layered perovskites.
