The instability of the metal halide perovskites upon exposure to moisture or heat strongly hampers their applications in optoelectronic devices. Here, we report large-yield synthesis highly water-resistant total-inorganic green luminescent CsPbBr3/CsPb2Br5 core/shell heteronanocrystals (HNCs) by developing an situ phase-transition approach. It is implemented via water-driven phase transition or...

The strong light scattering from SPR has received an extraordinary attention due to the useful applications in photodetectors and cell biomedical imaging. However, using require a high cross-section along with low absorption losses near resonance wavelength. In this paper, effective plasmonic of three-layered Au–Ag bimetallic nanoshells dielectric separate layer been studied quasi-static approx...

Nanoscale miniaturization of chalcogenide semiconductors such as lead sulfide (galena) can generate interesting quantum confinement effects in the field optoelectronic applications. In this work, we developed a process order to obtain SiO2 nanospheres coated with Galena, denominated core–shell system; is based on Stöber’s method, where magnetic stirring was replaced by an ultrasonic bath achiev...

We have developed a general theory of the plasmonic enhancement of many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. It is shown that this interaction has a resonant nature. We have also demonstrated that renormalized interaction is a long-ranged interaction whose intensity is considerably increased compared to bare Coulomb interaction ove...

Coated functionally graded materials (FGMs) are used in several industrial structures such as turbine blades, cutting tools, and aircraft engines. Given the need for analytical numerical analysis of these complex structures, a mathematical model tricoated FG is presented first time this paper. The objective work was to analyze analytically buckling problem unidirectional (1D), bidirectional (2D...
