Abstract:

The aim of the present study was to prepare nano-sized calcium fluoride (CaF2). Calcium fluoride nanoparticles were synthesized by CaCl2.6H2O and ammonium fluoride. Nanoparticles were synthesized by co-precipitation method. The synthesized nanocrystals were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). The crystallite size estimated using Scherer’s formula was found to be in the range of 20–30nm for nanocrystals synthesized by this method. The morphological features as studied using SEM revealed that the nanoparticles were agglomerated, crispy with porous.

Preparation and characterization of CaF2:Ce3+ nanoparticles with spectroscopic studies

In this research Calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. The mentioned nanoparticle were studied by fourier transform infrared spectroscopy (FTIR) , X-ray diffraction (XRD), absorption and photoluminescence spectra (PL) and Scanning electron microscopy (SEM). The XRD patterns indicate a typical cubic fluorite structure and no other...

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
