Broadband yellow and white emission from large octahedral tilting in (110)-oriented layered perovskites: imidazolium-methylhydrazinium lead halides

Autor: Dawid Drozdowski, Katarzyna Fedoruk, Adam Kabanski, Mirosław Maczka, Adam Sieradzki, Anna Gagor

Publikováno v: Journal of Materials Chemistry C. 11:4907-4915

New (110)-oriented 2D HOIPs exhibit record octahedral tilting implying broadband white and yellow photoluminescence, and an order–disorder symmetry-breaking phase transition at high temperatures.

Publikováno v: Inorganic chemistry. 61(39)

Two-dimensional (2D) lead halide perovskites are a family of materials at the heart of solar cell, light-emitting diode, and photodetector technologies. This perspective leads to a number of synthetic efforts toward materials of this class, including

Unusual isosymmetric order–disorder phase transition in a new perovskite-type dimethylhydrazinium manganese formate exhibiting weak ferromagnetism and photoluminescence properties

Autor: Maciej Ptak, Jan Albert Zienkiewicz, Adam Pikul, Katarzyna Fedoruk, Dorota Kowalska, M. Stefanski

Publikováno v: Journal of Materials Chemistry C. 9:6841-6851

We report the synthesis and investigation of the physicochemical properties of a novel hybrid organic–inorganic formate perovskite templated by the unsymmetrical 1,1-dimethylhydrazinium (DMHy+) cation, [DMHy]Mn(HCOO)3. This compound undergoes a fir

Publikováno v: CrystEngComm. 22:4716-4722

Indications of desirable polar order in ethylammonium C2H5NH3(EtA) metal formate [EtA][Na0.5Cr0.5(HCOO)3] and the lack of it in [EtA][K0.5Cr0.5(HCOO)3] raised important questions on the origin of structural phase transition and dipolar dynamics in th
