Abstract

In this work we report the synthesization process of nanocrstalline Nd:KTP powders by modified sol-gel method. The results of XRD studies indicate that KTP nanocrystallines doped by Nd has orthorhombic phase. By using micro Raman back scattering and FT-IR transmission spectroscopies, the lattice modes of the synthesized nanocrystalline products have been investigated. The structural and the grain sizes determination for the synthesized samples were measured using the XRD patterns and the Debye-Scherrer formula. These data are in close agreement with the grain sizes determined by the SEM slides. It can be claimed that XRD analysis and micro Raman backscattering spectroscopy are suitable methods to study the quality of nanocrystalline materials including KTP family
