Study on the Crystal Structure and Microstructure of SrB_4O_7 doped with Li by X-ray Powder Diffraction
Source abstract
Abstract
The doped Li ion has aneffect on both the crystal structure and property of SrB4O7. The crystal structure and microstructure of doped SrB4O7 was studied in detail from x-ray powder diffraction data. Its space group is Pmn21, cell parameters: a=1O.741(5)A, b=4.245(1)A, c=4.437(1)A, a little bigger than those of SrB4O7. Reasons for thesc changes were presented. In the cel1, Li ions occupy part of the vacancy between B-O layers; such a structure can improve the nonlinear optical coefficicnts. The errors of crystal data from references were also analyzed.
