Reversible thermochromism to tune the bandgap of organic–inorganic hybrid materials

Abstract

Organic-inorganic hybrid halide materials have been gaining tremendous interest due to unique optical, electrical and magnetic properties. However, large bandgap limits their applications. Here, we report a series of organic-inorganic...

Precise Design of Molecular Ferroelectrics with High TC and Tunable Band Gap by Molecular Modification

“…Typically, the determination of a compound’s band gap magnitude is contingent upon its inorganic structure. Therefore, the aspiration to precisely adjust the band gap magnitude may be achieved through minor modifications in cations. , This fine-tuning of the band gap structure is particularly important for optoelectronic applications. To elaborate on the essence of semiconductor properties of 1 , 2 , and 3 , their theoretical band gaps are calculated through the CASTEP module of Materials Studio.…”

Spectral Tunability, Luminescence Enhancement, and Temperature Sensitivity of Sb3+-Doped Bismuth-Based Halide Emission Crystals for Anti-Counterfeiting Applications

“…This distortion results in a change in the electronic structure and influences the energy levels involved in the PL process. 32,36 As a consequence, the emission wavelength shifts toward shorter wavelengths, corresponding to a blue-shift.…”

Tin-based organic–inorganic metal halides with a reversible phase transition and thermochromic response

“…[1][2][3][4][5][6][7][8][9][10] The perfect combination of organic and inorganic components provides feasibility for the occurrence of phase transition behavior. [11][12][13] At the same time, dielectric phase transition (thermally stimulated response) materials often bring about interesting physical properties such as fluorescence, [14][15][16] thermochromism, [17][18][19][20] ferroelectricity [21][22][23] and so on. [24][25][26][27][28][29][30] Compared with high-dimensional hybrid phase transition materials with limited organic ammonium species, the structures of low-dimensional compounds are more flexible and diverse.…”
