Structure Characterisation and Optical Properties of Eu3+-doped LaAlO3
In this paper,Eu3+-doped LaAlO3 powders which with the concentration of Eu3+ in the range of 0~5% were prepared by a new liquid mixing method.The structure of the LaAlO3 powders were investigated by X-ray diffraction (XRD),and the influence of the increase of temperature on the crystal structure were also studied.We found that the powders crystallized above 800℃ which means higher temperature can improve the crystallization.The influences of the increasing Eu3+ concentration were also studied through the XRD patterns.The average sizes of the samples were also calculated by the Sherrer equation.The optical properties of different concentration of Eu3+-doped LaAlO3 particles were investigated through the reflection spectra.
