Raman fingerprint of stacking order in HfS2-Ca(OH)(2) heterobilayer
(American Physical Society, 2019-05)
Using density functional theory-based first-principles calculations, we investigate the stacking order dependence of the electronic and vibrational properties of HfS2-Ca(OH)(2) heterobilayer structures. It is shown that ...
Gd3+-Doped alpha-CsPbI3 nanocrystals with better phase stability and optical properties
(American Chemical Society, 2019-10)
Black alpha-CsPbI3 perovskites are unable to maintain their phase stability under room conditions; hence, the alpha-CsPbI3 phase transforms into a thermodynamically stable yellow delta-CsPbI3 phase within a few days, which ...
Experimental and first-principles investigation of Cr-driven color change in cesium lead halide perovskites
(American Institute of Physics, 2019-06)
Herein, we report room temperature Cr-doping for all-inorganic perovskites that have attracted great attention in recent years due to their extraordinary optical properties, low cost, and ease of synthesis. Incorporation ...
Color-tunable all-inorganic CsPbBr3 perovskites nanoplatelet films for photovoltaic devices
(American Chemical Society, 2019-08)
Herein, we demonstrate a novel coating approach to fabricate CsPbBr3 perovskite nanoplatelet film with heat-free process via electrospraying from precursor solution. A detailed study is carried out to determine the effect ...
