In the last few years, the Synchrotron Radiation Laboratory of IHEP has made a series of in-depth study of nano particles of ZnO, NiO, Fe₂O₃, CeO₂, TiO₂, etc. in terms of the structure and property and put forward a creative idea. For the first time in the world the comparative study of the total electron yield of O 1s edge was performed and the information of different electron structures and hybrid orbits was obtained for the nano phase and bulk phase. For the first time it was proved experimentally that there exists the electron quadrupole transition in TiO2 nano particle.

　　The other achievement is the preparation of Ni nano wire for the first time in the world using chemical method. The wire is 30 – 50 nm in diameter and 2.7 mm long. A strong luminous phenomenon was observed in the range of 340 nm to 390 nm. This band is between blue and violet. During the experiment on the total electron yield of O 1s edge for NiO bulk and Ni nano wire, it was found that there was a hybrid peak a of Ni 3d orbit and O 2P orbit, thereby proving that there is a less than 0.6 nm layer of NiO outside the Ni nano wire. 

　　With the support from the CAS Nano Center, the SR Lab has done some pioneering research on carbon nano tube for the past year. During the systematic study of the absorption spectrum of the total electron yield of C ls edge for carbon nano tube material, sp2 hybrid near 286 eV and the bonding structure between the residual raw material and nano tube were successfully observed. This kind of research might open up a new field for the study of nano tube material and the structural characterization. Experimental study was also carried out on L3-edge of Ce atom in nano porphyrin molecule and its nano molecular structure was quantitatively obtained for the first time through ab inition computation.
