Anomalous and Colossal Thermal Expansion, Photoluminescence, and Dielectric Properties in Lead Halide-Layered Perovskites With Cyclohexylammonium and Cyclopentylammonium Cations
Cuquejo-Cid, Alberto; García-Fernández, Alberto; Popescu, Catalin; Bermúdez-García, Juan Manuel; Señarís-Rodríguez, M. A.; Castro-García, Socorro; Vázquez, Digna; Sánchez-Andújar, Manuel (Elsevier, 2022-06-03)[Abstract] A detailed study of lead halide-layered perovskites with general formula A2PbX4 (where A is cyclohexylammonium (CHA) or cyclopentylammonium (CPA) cation and X is Cl− or Br− anion) is presented. Using variable ... -
Design, synthesis and characterization of hybrid organic-inorganic materials for energy and environmental applications
García-Fernández, Alberto (2018)[Abstract] The main objective of the present Ph.D. Thesis is the study of functional hybrid organicinorganic materials, and more specifically, the modulation of the properties of those materials through the design of ... -
Diimidazolium Halobismuthates [Dim]2[Bi2X10] (X = Cl–, Br–, or I–): A New Class of Thermochromic and Photoluminescent Materials
García-Fernández, Alberto; Marcos-Cives, Ismael; Platas-Iglesias, Carlos; Castro-García, Socorro; Vázquez, Digna; Fernández, Alberto; Sánchez-Andújar, Manuel (American Chemical Society (ACS), 2018-06-12)[Abstract] We present a novel family of polyhalide salts of Bi(III) with the general formula [Dim]2[Bi2X10], where Dim2+ is the diimidazolium cation (C9H14N4)2+ and X is Cl–, Br–, or I–. Single-phase materials are easily ... -
Narrowing the Tolerance Factor Limits for Hybrid Organic-Inorganic Dicyanamide-Perovskites
García Ben, Javier; García-Fernández, Alberto; Dafonte Rodríguez, Pedro; Delgado Ferreiro, Ignacio; Cappel, Ute; Castro-García, Socorro; Sánchez-Andújar, Manuel; Bermúdez-García, Juan Manuel; Señarís-Rodríguez, M. A. (Elsevier, 2022-10-11)[Abstract] In this work we focus in setting the limits of the tolerance factor and the size of the A-cations that stabilize the perovskite structure in hybrid dicyanamide compounds [A][Mn(dca)3]. For this purpose, we propose ... -
Near-Room-Temperature Reversible Giant Barocaloric Effects in [(CH₃)₄N]Mn[N₃]₃ Hybrid Perovskite
Salgado-Beceiro, Jorge; Silva, Ariel Nonato Almeida de Abreu; Silva, Rosivaldo Xavier da; García-Fernández, Alberto; Sánchez-Andújar, Manuel; Castro-García, Socorro; Stern-Taulats, Enric; Señarís-Rodríguez, M. A.; Moya, Xavier; Bermúdez-García, Juan Manuel (Royal Society of Chemistry, 2020-09-25)[Abstract] We report giant reversible barocaloric effects in [(CH₃)₄N]Mn[N₃]₃ hybrid organic–inorganic perovskite, near its first-order cubic-monoclinic structural phase transition at 𝑇₀ ∼ 305 K. When driving the transition ... -
Raman Spectroscopy Studies on the Barocaloric Hybrid Perovskite [(CH₃)₄N][Cd(N₃)₃]
Silva, Rosivaldo Xavier da; Paschoal, Carlos William de Araujo; Santos, Clenilton; García-Fernández, Alberto; Salgado-Beceiro, Jorge; Señarís-Rodríguez, M. A.; Sánchez-Andújar, Manuel; Silva, Ariel Nonato Almeida de Abreu (MDPI, 2020-10-16)[Abstract] Temperature-dependent Raman scattering and differential scanning calorimetry were applied to the study of the hybrid organic-inorganic azide-perovskite [(CH₃)₄N][Cd(N₃)₃], a compound with multiple structural ... -
