Abstract ： The composition of Sr(NO3 )2 crystals grown from an aqueous solution doped with Ba2+ and Pb2+ were characterized by electron probe microanalysis technique. It was found that Ba2+ is enriched in {100} sectors and Pb2+ in {111} sectors. Raman spectra of different parts in 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.
