Structural, Thermal and Functional Properties of a Hybrid Dicyanamide-Perovskite Solid Solution

Crystals, 2022
In Solid-State Chemistry, a well-known route to obtain new compounds and modulate their properties is the formation of solid solutions, a strategy widely exploited in the case of classical inorganic perovskites but relatively unexplored among emergent ...

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

Advanced Functional Materials, EarlyView.
CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Crystalline structure and electrical properties of Dy_1-XCa_XMnO₃ solid solution

Boletín de la Sociedad Española de Cerámica y Vidrio, 2002
Solid solutions corresponding to the Dy1-xCaXMnO3 system, x=0.0 to 0.60 have been studied. The powders were prepared by solid state reaction of the corresponding oxides and carbonates. Sintered bodies were obtained by firing between 1250 and 1450ºC.

Water Adsorption‐Induced Color Sensor: Insight Into the Sensing Mechanism and Interfacial Engineering for Improved Responsiveness

Advanced Functional Materials, EarlyView.
We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...
