Abstract

In this work the synthesization process of nanocrstallite Nd:KTP powders by modified Pechini method was studied. The results of XRD studies indicate that KTP nanocrystallites doped by Nd has orthorhombic phase. The structural and lattice modes of the synthesized nanocrystallite products were investigated by using Micro Raman back scattering and FT-IR transmission spectroscopies. SEM imaging technique was applied for the observation of grain sizes and the morphology of the nanoparticles. The Debye-Scherrer formula was used to confirm the grain sizes determined by the SEM slides. In overall conclusion, it can be claimed that XRD, SEM and back scattering Raman spectroscopy are suitable methods to study the quality and characterization of nanocrystallite materials such as KTP family nanocrystals.
