EPR OF Mn2+ IN NANO-SIZED ZINC SULFIDE WITH PLANAR LATTICE DEFECT
Abstract
EPR of Mn2+ ions in three cubic nano-ZnS samples was studied. The samples were obtained by different technological processes and the sized of nanoparticles were different. Manganese was in the samples as an uncontrolled impurity. The EPR spectra of all samples can be described by two components - the spectrum of Mn2+ in the cubic surrounding, Mn2+ (C), with the parameters g = 2.0022 ± 0.0002,A = (-63.5 ± 0.5)´10-4 cm-1 , b40 ³ 3.5´10- 4 cm- 1 and the spectrum of Mn2+ ion associated with planar lattice defect of the packaging, Mn2+ (D). The parameters of Mn2+ (D) spectrum are: g = 2.0022±0.0002, A = (-63.5±0.5)´10- 4 cm- 1 , b20 = = (-36±1)´10- 4 cm- 1 . The ratio of centers amount Mn2+ (C)/Mn2+ (D) for the samples studied was 2.1:1 (sample 1) and 1.7:1 (samples 2 and 3). Planar packing defects are typical lattice defects in cubic nano-ZnS. EPR of Mn2+ allows one to monitor the presence of these defects.
