Cooperative coupling of anisotropic phonon modes intensifies visible thermochromism in layered α-MoO₃

Abstract

Applications that provide versatile, high temperature warnings requires the development of thermochromic materials based on solid-state oxides. To boost the visible thermochromic properties, a fundamental approach to reveal the unclear...

Thermochromism and thermal crystal structure evolution of YIn0.9Mn0.1O3

“…Thermochromism is the change in the color of a material when the temperature changes, which has been observed in a variety of materials ranging from inorganic, organic, organic-inorganic hybrid, to polymeric materials. [1][2][3][4][5][6] Materials with pronounced thermochromism have attracted attention because of their potential applications, such as inks, clothing, smart windows, and temperature indicators. 5,[7][8][9][10][11][12][13][14] Generally, thermochromism originates from a temperature-induced change in the electronic structure that governs the optical properties.…”

“…Such a change in electronic structure is caused by several mechanisms. Examples for the case of inorganic materials include a semiconductor-to-metal phase transition in VO 2 , 8,12) cooperative coupling of anisotropic phonon modes in α-MoO 3 , 6) a structural phase transition in CuMo 1−x W x O 4 , 3) and a gradual change in the ligand environment in ruby. 2,13) YIn 1-x Mn x O 3 is a newly discovered inorganic blue pigment and is marketed under the name "YInMn blue" due to its chemically stable nature.…”

One-step hydrothermal growth of porous nickel manganese layered double hydroxide nanosheet film towards efficient visible-light modulation

“…[1][2][3] Recently, energy-storage EC devices integrating EC and energy-storage functions in a single platform, such as EC batteries and EC supercapacitors, have developed rapidly for both energy-saving and energystorage applications. [4][5][6] As the most important component, EC materials have been widely investigated as some of the promising smart materials, including transition metal oxides (WO 3 , 7-9 V 2 O 5 , 10 NiO, 11 MoO 3 , 12,13 etc. ), conducting polymers, 14 small organic molecules, [15][16][17] Prussian blue (PB), [18][19][20] and so on.…”

High-Pressure Route to Irreversible Thermochromic Materials

“…Many materials change color when the temperature changes, a phenomenon known as thermochromism. This occurs in a wide range of materials, including inorganic, organic, and organic–inorganic hybrids. − Recently, materials with pronounced thermochromism have been extensively explored due to their potential applications such as smart windows and clothing, − and new mechanisms for achieving pronounced thermochromism have been discovered. Examples for the case of inorganic materials include cooperative coupling of anisotropic phonon modes in α-MoO 3 , spin crossover in LaGa 1– x Co x O 3 , a semiconductor-to-metal phase transition in VO 2 , , and a structural phase transition in CuMo 1– x W x O 4 …”
