Introduction The study on the luminescence of rare earth complex, being the cross science of the luminescence of inorganic materials, organic materials and organism, is very important for the fundamental and applied research.
Rare earth materials are valued by their luminous intensity, good monochromaticity and so on , are widely applied in industry, agriculture, biology domain and so on[1~2].
And in the packing and printing fluorescence ink aspect, as fluorescence material, rare earth complexes have the narrow emission spectrum, the high excitation purity and fluorescence efficiency and stability , and they are green[3~4].

Rovisco Pais, 1049-001 Lisboa, Portugal 2 Department of Materials Science and Engineering, Zhejiang University, 310027 Hangzhou, China Keywords: Alkaline fuel cell, hydrogen storage alloys, electrode properties Abstract.
It was suggested that hydrogen storage intermetallic compounds could be used as electrocatalysts to substitute noble metal for fuel cell anode materials [1,2].
TiFe and TiFe-based alloys are considered as appropriate materials for hydrogen storage application because of their high energy density, good hydrogen absorption-desorption capability, low price and environmental compatibility [3,4].

Introduction Nanocrystalline magnetic materials have outstanding properties thanks to their small grain size.
It is assumed a ferromagnetic material with uniaxial anisotropy.
In other words, the models of Fig. 2 are only valid for phases with very small domain wall thickness, i.e., materials with very high magnetocrystalline anisotropy, as Nd2Fe14B and SmCo5 for example.
