چکیده
Abstract Widely used as a medicinal plant in Ayurveda black pepper is also main content of spices. Easily available such kind herb studied the first time luminescence point view. In this paper, we have characteristics samples and check their properties for LED applications which are synthesized four parts 1) Pure powder 2) Black Pepper Solution by ethanol 3) Europium (Eu) doped solution 4) thin film. The were characterized Photoluminescence (PL) techniques. PL all showed interesting results. emission at 471nm under 421nm excitation wavelength. shows an band around 430nm 397nm excitation. two peaks 516nm 658nm 440nm Thin-film pure 454nm 390nm CIE Chromaticity Coordinates other color co-ordinates near blue white region visible spectrum. These chromaticity demonstrate high spectral characterization developed materials purity excellent co-ordinates. entire photoluminescence results indicated that promising potential applications.

Given the growing importance of photocatalysts in the industrial wastewater treatment, in this study, TiO2-CuO (TC) composite nanoparticles were synthesized by sol-gel method. Tetrabutyl orthotitanate (TBT), copper nitrate-3hydrate and ethanol were used as titanium dioxide precursor, copper oxide precursor and solvent, respectively. The structural, optical, photocatalytic activity and BET-BJH...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

The efficiency of using a composite of carbon black and sodium bentonite in treating drinking water contaminated with lead and copper ions was analysed. The effects of pH, contact time, concentration and adsorbent dosage using an adsorbent composite of 20 % sodium bentonite and 80 % carbon black were studied. The adsorption data was tested with respect to Langmuir, Freundlich and Temkin iso...
