| 摘 要： | The compositions of Sr(NO3)2 crystals grown from an aqueous solution doped with Ba^2 and Pb^2 were characterized by the electron probe microanalysis technique.It was found that Ba^2 is enriched in {100} sectors and Pb^2 in {111} sectors.The Raman spectra of different parts of these crystals at room temperature in the ranges of 1038-1070cm^-1 and 650-1150cm^-1 were investigated.The results indicated that barium and lead shift the Raman dominating peaks to the lower frequency and broaden the full width at half maximum.Furthermore,barium probably degrades the properties of the Sr(NO3)2 Raman shifter while lead is anticipated to improve it.
