Spin-crossover nanoparticles represent a very versatile class of switchable nanomaterials. Here we describe the synthesis and characterization of Fe(II) coordination complex nanoparticles displaying above room temperature bistability. Synthesis of the [Fe(pz){Au(CN)2}2] (pz – pyrazine) nanoparticles was performed in solutions using Triton X-100 sur...
The present study discusses the synthesis of lithium-doped barium stannate titanate BaTi0.89Sn0.11O3 (BTS11) using sol–gel synthesis route and explores the influence of the lithium content on their structural, morphological, ferroelectric, optical, and electrical properties. The phase of the sol–gel prepared samples with different atomic compositio...

A supercapacitor (SC) is considered to be one of the best energy storage devices due to its high-power density, long lifespan, fast charge storage capability, and eco-friendliness. Ceramics with low-cost, nontoxic, high efficiency, and stability are the suitable and promising materials for performed supercapacitors at room temperature. As proposal,...
Vanadium pentoxide (V2O5) attracts considerable attention in electrochromism due to its multicolor aspects and high ion storage capacity for the counter electrode. In this work, pure and Fe-doped V2O5 films are deposited by radiofrequency magnetron co-sputtering. The influence of Fe doping on the structural and electrochemical properties of V2O5-ba...

Lead borate glass is the best radiation shielding glass when lead is in high concentration. However, it has low transparency after radiation exposure. Radiation decreases transparency due to chemical and physical changes in the glass matrix, such as creating or healing defects in the glass network. The addition of rare earth elements like cerium an...
Plasmonic anisotropic nanocomposites containing in particular nanorods and nanowires are gaining increasing interest due to their remarkable physical and optical properties. In this paper, we introduce a novel effective medium theory which we call “Orientation and Shape Distributions Effective Medium Theory” (OSDEMT), to describe the optical proper...

The present work elucidates a study on the synthesis and characterization of nanostructured NiS thin films, an optical absorber material. NiS films have been deposited on glass substrates using a simple and cost-effective chemical solution route. The deposition process has been accomplished using an aqueous solution of nickel chloride, thiourea, am...
In this work, an investigation of the photovoltaic (PV) performance of organic solar cells (OSCs) based on PM6:Y7, in combination with a conductive atomic force microscopy (c-AFM) study, is presented. OSCs were fabricated and tested under regular atmospheric conditions, employing the conventional structure glass/ITO/PEDOT:PSS/PM6:Y7/PFN/Field’s met...
Organo-halidové perovskity (OHP) jsou perspektivními materiály v oblasti fotovoltaiky, LED, fotodetektorů, scintilátorů a laserů. Od jejich prvního použití v solárním článku v roce 2006 se účinnost přeměny energie na nich postavených solárních článků zvýšila z přibližně 2 na 26 %. Navzdory výraznému zlepšení však stále zůstává mnoho nezodpovězených...
The incorporation of boron into a diamond lattice holds the potential to advance X-ray optics, offering the capability to manipulate various parameters of the lattice. This includes enhancing near-infrared absorption relative to pure diamond, thereby enabling Q-switchable optics. The use of MeV boron implantation emerges as a promising method for p...
