Magnesium nano ferrite Mg1−xFe2O4 with deficient Mg (0 ≤ x ≤ 0.5) has been prepared with the co-precipitation method. The Mg deficiency was examined from the samples elemental compositions obtained by energy-dispersive X-ray spectroscopy. The i
Samples of non-stoichiometric nano CdS1 − x were synthesized by a simple thermolysis method by lowering the ratio of thiourea relative to cadmium acetate as starting precursors; Cd(Ac):(1-x) thiourea (x = 0.0, 0.03, 0.05 and 0.1). X’pert HighScor

CdS and Cd0.95Mn0.05S were synthesized using a thermolysis procedure in the air and underflow of nitrogen. Rietveld analysis for X-ray diffraction data revealed that all samples have two phases (hexagonal wurtzite and cubic zinc blende). The effect o
