All-inorganic perovskite has attracted significant attention due to its excellent nonlinear
optical characteristics. Stable and low-toxic perovskite materials have great application …

To enhance the optical limiting behavior triggered by nonlinear absorption (NA), wide-band
gap MnO2 nanoparticles were incorporated into polyvinylpyrrolidone (PVP) polymer …

Abstract CdS/PEG, 4 and 7 mol% Ce doped CdS/PEG nanocomposite films were
synthesized by in situ method. The XRD pattern confirmed the cubic structure of the CdS and …

We report a versatile approach to obtain MoO3 nanostructures such as nanorods,
nanowires, nanobelts, and nanotubes in thin film form on glass substrates, by incorporating …

Stable films containing CdS quantum dots of mean size 3.4 nm embedded in a solid host
matrix are prepared using a room temperature chemical route of synthesis. CdS/synthetic …

In order to enhance the optical nonlinearity of the nickel oxide, NiO nanoparticles doped with
Cr/Sb were synthesized by hydrothermal method. Their nanocomposite films which have …

We demonstrate the variations of the nonlinear optical parameters in the suspensions and
thin films containing PbS quantum dots of different sizes (9 and 2.5 nm). We show that these …

A facile biomolecule-assisted hydrothermal route followed by calcination has been
employed for the preparation of monoclinic yttrium oxysulfate hollow spheres doped with …
