Metal-halide perovskites have recently demonstrated great potential for a wide variety of optoelectronic applications, with their layered subfamily offering improved stability as compared to three-dimensional analogues. Among the compounds, subclass <1 0 0> terminated compounds are currently dominating field, while 1 is comparably much less explored. Here, we report on synthesis (FA)3(HEA)2Pb3I...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
The existence of polar nanoregions (PNRs) is the most important characteristic ferroelectric relaxors; however, size determination and dynamic PNRs remain uncertain. Herein, it revealed that a re-entrant relaxor behavior ferroelectric–paraelectric transition coexist in complex perovskite oxide 0.6Bi(Mg1/2Ti1/2)O3-0.4PbTiO3. Two dielectric anomalies, 1) low-temperature 2) high-temperature diffus...
