“…The yellow band emission at 588 nm might be due to the de-excitation of electrons via the surface/defect states present in the nanocrystals [23]. The peaks at 615 and 621 nm may be attributed to surface states which arise from the deep traps formed due to Fe vacancies [24].…”

Pure CdO nanopowder and CdO-Fe 3 O 4 nanocomposite were synthesized by a cost effective chemical method, and the samples were characterized by XRD, SEM, TEM, FT-IR, UV-Vis-NIR and PL. Also, magnetic and photocatalytic properties of the synthesized samples were studied. XRD patterns of the composite confirm the presence of diffraction peaks related to both CdO and Fe 3 O 4 . EDX spectrum confirms the presence of the elements Cd, O and Fe in the composite. Peaks related to Cd-O and Fe-O bonds were observed respectively at 688 cm −1 and 592 cm −1 in the FT-IR spectrum. The paramagnetic behavior of pure CdO becomes ferromagnetic when coupled with Fe 3 O 4 . The composite exhibited a high photodegradation efficiency of 92.85 % against the degradation of methylene blue dye under visible light radiation.

Investigations on thermal reactivity of Si/C/N nanopowders produced by laser aerosol or gas interactions

Ultrafine SiCN particles with various compositions, synthesised by laser pyrolysis in interaction either with gaseous or liquid reactant, were heat treated at temperatures between 300 and1773 K. Thermogravimetric measurements performed under inert (helium) atmosphere, showed that the best thermal stability was exhibited by nanopowders prepared from gaseous precursors (SiH 4 , CH 3 NH 2 , NH 3 ). Mass spectrometry analysis data revealed that nanopowders derived from a mixture with ammonia and hexamethyldisilazane (HMDS) contained more N-H and C-N groups than those obtained without ammonia. The loss of hydrogen clearly dominated amongst the observed losses in all the examined samples at all temperatures. This study indicates that thermal degradation of such silicon based systems is not a single reaction but the net result of a number of reactions.
