Ion migration and phase separation in perovskite materials have negatively affected the solid-state lighting display. Studying photo- thermal-induced degradation is considered as a promising approach to understanding luminescence mechanism promoting practical applications. Herein, Mn-doped two-dimensional PEA2PbX4 (X = Cl, Br, I) microcrystals with changing halogen composition were synthesized by an acid-assisted post-processing strategy. Then, was studied using steady-state time-resolved...
The room temperature gas sensing properties of the hollow SnO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> /ZnO heterojunction-based chemiresistive sensors under ultraviolet (UV) radiation were investigated. heterojunctions fabricated using template-assisted process followed with a hydrothermal treatment. sensor this core-shell showed much higher response to formaldehyde UV illumination compared that without UV. Moreover,...
Low-dimensional metal halide perovskites are widely studied due to their excellent optoelectronic properties and environmental stability. Recently, transition Mn2+ ions were introduced into two-dimensional (2D) perovskite modify photophysical properties. However, the Mn luminescence mechanism still needs further exploration, which includes role played by A-site cation engineering. Herein, we prepared 2D microcrystals with four cations: butylamine (BA), phenethylamine (PEA), octylamine (OCA)...
The hollow ZnO@TiO2 heterostructured nanospheres were synthesized by hydrothermal method using carbon as sacrificed templates. With UV activation, the response of based chemiresistive-type sensors to 10 ppm formaldehyde is 11.02 at room temperature which 5.48 times larger than that pure ZnO. and recovery time significantly reduced 14 s 16 s. Selectivity, stability repeatability sensor under UV-activation have also been examined. sensing mechanism investigated AC impedance spectroscopy,...
Au-decorated hollow TiO 2 nanospheres were synthesized via a template method, Afterwards, the surface of was decorated with different amounts Au nanoparticles by reduction method. The characterization results show that diameter is 150-200 nm, thickness shell layer 10-15 size about 15 nm. Gas sensing properties present 1 mol% based sensor exhibited better performance to formaldehyde under Ultraviolet (UV) irradiation at room temperature. response 5 ppm 8.5, which three times higher than pure...
Introduction Formaldehyde (HCHO) is an important chemical raw material that has a wide range of applications in interior decoration materials such as adhesives, building and coatings. Long-term exposure to formaldehyde can cause headaches, memory loss, especially harmful for pregnant women infants [1]. Therefore, timely accurate detection indoor environments very important. In this aspect, titanium dioxide (TiO 2 ) typical n-type semiconductor. Due its good photocatalytic performance, low...
