In this "nano idea" paper, three concepts for the preparation of methylammonium lead halide perovskite particles are proposed, discussed, and tested. The first idea is based on the wet chemistry preparation of the perovskite particles, through the addition of the perovskite precursor solution to an anti-solvent to facilitate the precipitation of the perovskite particles in the solution. The sec...
Flashing or thermodynamic breakup of a liquid jet occurs when a pressurized subcooled or saturated liquid is released to a lower pressure, resulting in violent vapor nucleation, expansion, and break up of the liquid phase. Flashing is known to produce very fine droplet atomization, often not possible by traditional mechanical means. In this work, flashing atomization is introduced in a spray bu...
In present study spray pyrolysis technique was employed to prepare pure and doped CdSnO3 thin films. The spray pyrolyzed thin films were observed to be nanostructured in nature with particle size less than 10 nm and characterized to investigate its structural, microstructural and chemical properties by means of XRD, SEM/EDS, TEM and surface profilometry. Pure and Zn doped CdSnO3 nanostructured ...
Strontium titanate polycrystalline thin films were prepared by sequent deposition of three TiO2/SrO/TiO2 layers using spray pyrolysis technique. Deposition parameters such as: precursor solution, deposition temperature, flow rate of solution and annealing conditions were optimized to obtain homogeneous transparent films. Prepared thin films have granular microstructure. The optical transmittan...
Cobalt doped zinc oxide thin films have been deposited using spray pyrolysis method. These single phasic films exhibited [100] preferential texture and small decrease in the lattice parameter on cobalt substitution. The films having different Co concentration have almost similar surface morphology and microstructure. These Zn1-xCoxO (x B 0.10) thin films distinctly showed ferromagnetic characte...
The growth and structural study of Nickel doped Cobalt ferrite thin films on glass substrate using spray pyrolysis technique have been done. The structural studies confirmed the growth of polycrystalline film having cubic structure with Fd3m space group. The x ray density was found to increase with Ni concentration, where as the reduction, in crystalline size, was found in XRD m...
Effect of substrate temperatures, spray rates, solution volumes, and nickel concentration on structural optical properties NiO thin films prepared by pyrolysis
CuZnO (CZO) films have attracted increasing amounts of attention due to their promising potential applications in semiconductor devices. ZnO shows n-type conductivity, and attempts have been made to dope several elements in ZnO to improve the electrical properties. This study investigated the electrical property transitions of CZO films and determined the copper concentration at which the condu...
