In the current study, concentrated Nd:YAG laser pulses at 500 mJ with a second radiation at 1064 nm (pulse width 9 ns) and repetition frequency (6 Hz) for 300 laser pulses incident on the target surface were employed to coat glass substrates with MnO thin films. Using an X-ray diffractometer (XRD), an atomic force microscope (AFM), and a UV-Vis spectrophotometer, the structural, morphological, and optical characteristics of the films doped with different concentrations of Cu content (0.03, 0.05, 0.07, and 0.09) were examined. The results show that the films are polycrystalline, with the largest peak appearing at an angle of 35.31, or a reflection of (111). The crystalline size of the deposited thin films was calculated using Debye Scherer formula and found to increase from 11.8 nm for undoped MnO2 to 29.6 nm for doped (MnO) with the increase of Cu content from x=0 to x=0.09 at preferred orientation of (111). All the samples have a cubic structure. Also, the results showed that Cu content of the films affects the surface morphology. From the results of AFM analysis, it was found that the roughness and average diameter change when adding Cu to the structure, with the highest value occurring at Cu ratio 0.09 equal to 65.40 and 71.21 nm, respectively. UV–Vis spectrophotometer was used to investigate the optical transmission. It was found that when Cu content of films increased, the transmittance of films decreased. Hall Effect measurements show that all prepared films at RT have two type of conductivity P-type and n-type. The electrical characteristics of the (MnO)1-xCux/Si heterojunction Solar Cell have been studied and found that the efficiency (η) decreases with the increase of Cu content.

“…Where: E opt is the optical energy gap, B is a constant which depends on material structure and r is an index which can be assumed to have values of 1/2, 3/2, 2 and 3, depending on the nature of the electronic transition responsible for the absorption. Also, r = 1/2 for allowed direct transition, r = 3/2 for forbidden direct transition and r = 3 for forbidden indirect transition, with r = 2 refers to indirect allowed transitions [14].…”

Tin oxide (Sn) nanoparticles were prepared by pulsed laser ablation (PLA) method at different laser energies (400-700mJ). (UV, XRD, AFM, SEM, EDS) methods were employed to determine the properties of nanomaterials. The optical properties showed that the energy gap decreased with increasing laser power; the structural properties showed the relationship between density and angle; Miller's coefficients for net angles were determined and the morphology properties showed the element's surface shape and surface roughness. Also, Tin oxide nanoparticles with added to Staphylococcus aureus bacteria isolated from the ear and cultured by striking method on nutrient agar to know the effect of tin oxide nanoparticles on the growth of this bacteria. The results showed that tin (Sn) oxide nanoparticles had a role in decreasing the growth of bacteria on cultured media using the laser energies of (400mJ, 500mJ and 600mJ), but at an energy of 700mJ a clear zone (no growth) of bacteria on cultured media was noted, indicating 100% bacterial killing.
