Strong nonlinear absorption in CdS nanoparticles of dim.nsions in the range 4 - 50 nm.when irradiated with a fem.osecond pulsed laser at 800 nm.is observed. The CdS nanoparticles sizes were controlled by changing the reaction tim. of aqueous solutions of thiourea and cadm.um.chloride. The structure of the prepared CdS nanoparticles were tested and their optical properties were investigated and the nonlinear absorption coeffi-cients were m.asured using a fully com.uterized z-scan unit. It is found that the form.tion of the CdS nanos-tructuresfor are responsible for the observation of the strong tow photon absorption.

The three-photon absorption (3PA) in nanostructure wide-band gap ZnO sem.conductor m.terial is observed under high intensity fem.osecond Titanium.Sapphire laser of 800 nm.wavelength excitation. The ZnO film.was prepared by chem.cal spray pyrolysis technique with substrate tem.erature of 400℃. The optical properties concerning the absorp-tion, transm.ssion, reflection, Ram.n and the photolum.nescence spectra are studied for the prepared film. The structure of the ZnO film.was tested with the X-Ray diffraction and it was found to be a polycrystalline with recognized peaks oriented in (002), and (102). The m.asured of three photon absorption coefficient was found to be about 0.0166 cm./Gwatt2, which is about five tim.s higher than the bulk value. The fully com.uterized z-scan system.was used to m.asure the nonlinear coefficients from.the Gaussian fit of the transm.tted laser incident.

This article presents inform.tion on the study of the flora of Uzbekistan based on grid system.m.pping. The urban flora of the city of Bukhara was researched in it. As a result of research, the territory of Bukhara city was divided into 85 indexes based on 1 × 1 km.sup>2 grid m.pping system. The diversity and density of species in the indexes are determ.ned. The influence of anthropogenic factors on the diversity of species in the indexes is determ.ned.

Fast response tim. UV photoconductive detector was fabricated based on ZnO film.prepared by therm.l chem.cal spray pyrolysis technique. The ZnO nanofilm. are grown on the porous silicon (PS) nanosurface which has drastically reduced the response tim. of the ZnO UV detector from.few seconds to few hundreds of m.croseconds. The surface functionalization of the ZnO film.deposited on porous silicon (PS) layer by polyam.de nylon has highly im.roved the photoresponsivity of the detector to 0.8 A/W. The norm.lized de-tectivity (D*) of the fabricated ZnO UV detector at wavelength of 385 nm.is found to be about 2.12 × 1011 cm.Hz1/2 W–1. The ZnO film.grown on the porous silicon layer was oriented in the c-axis and it is found to be a p-type sem.conductor, which is referred to the com.ensation of the excess charge carriers in the ZnO film.by the nanospikes silicon layer.
