The effect of mole ratio variation of poly vinyl alcohol as capping agent on size and shape of KTiOPO4(KTP) nano particles synthesized by co-precipitation method

KTiOPO4(KTP) nanoparticles were synthesized by co-precipitation method using poly vinyl alcohol (PVA) as capping agent. Different mole ratios of PVA (1:3,1:2 and 1:1) with respect to titanium ion were used. XRD patterns confirmed the formation of KTP structure. By change of capping agent mole ratio Spherical-form and polyhedral – form of KTP nanoparticles were observed. Biggest and smallest grain size and particle size was obtained by 1:3 and 1:1 mole ratios.
