概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
Employ electron spin resonance (ESR) test to study the defects in YTOSsamples, mainly including O vacancies and Ti3+ species. These defects affected by heating time during the preparation process of YTOS were discessed here.
実験 / Experimental
YTOS powder samples prepared from differen heating durations were weighed, recoreded, and added into nuclear magnetic tubs for ESR testment. Obtiaend signal data were recorded.
結果と考察 / Results and Discussion
The electron spin resonance (ESR) was performed to study the defects in Y2Ti2O5S2 (YTOS) samples with different synthetic procedures. As for the SSR samples, O vacancy was detected at 3514 G (g=2.01) and the signal intensity was increased with decreasing the heating duration. In the case of Flux-1/y samples, no obvious O vacancy signal was observed, but the signals for Ti3+ were observed at 3600 and 3680 G (g=1.96 and 1.92, respectively), and the signal strength was decreased with the decrease in the heating duration.
