在本文中,我们提出了电子顺磁共振（EPR）和M ssbauer谱（ö传输方法,在散射方法,TMS和测量CEMS）实验对57Fe的（0.1– 在1.%）掺杂纳米锐钛矿型TiO2,
In this paper we present electron paramagnetic resonance (EPR) and Mössbauer (transmission method,TMS and measurements in the scattering method,CEMS) experiments on 57Fe (0.1–1 at.%) doped nanocrystalline anatase-type TiO2,
