NMR study of bistable defects under in situ illumination

Alloyed Crystalline CdSe1‐xSxSemiconductive Nanomaterials – A Solid State113Cd NMR Study

“…Plots energy gaps ( E g ) vs T 1 are all linear with coefficients of determination R 2 value 0.88223, E g vs 1/ T 1 with R 2 =0.97665 and E g vs log(1/ T 1 ), R 2 =0.99749 (See SI, Figure S13). This data suggests that the materials’ spin‐lattice relaxation times may be related to the energy gaps . However, little literature data is available and here only three samples were studied; more research as well as theoretical calculations are needed to ascertain whether this is a true correlation or merely coincidental.…”

“…Spin-lattice relaxation times T 1 have been reported in the pure metal, 4,5 in Cd x Mo 6 Se 8 ͑x =1,2͒, 6 and in a variety of doped semiconductor crystals. 7,8 In the experiments reported here, 111 Cd and 113 Cd spectra and magnetization recoveries for CdMoO 4 were observed using static samples with a Bruker MSL-300 NMR spectrometer at a magnetic field of 7.049 T, where the proton resonance frequency is 300.130 MHz. Both the 111 Cd and 113 Cd spectra in CdMoO 4 are narrow and can be fitted to Lorentzians having a half width at half height of about 250 Hz.…”
