Abstract

The main objective of the present study was to synthesis the different immobilization of Sr+2in LiSr2(PO4)3crystalsusing soft hydrothermal methodat moderate pressure and temperature conditions.The powder X-ray diffraction confirms that, the synthesized LiSr2(PO4)3material has very good phase purity and crystalline with rhombohedralstructure.The energy-disperse X-ray (EDX) spectroscopic analysis shows their elemental composition correlating well with that of the strontium. Observation through a Scanning Electron Microscope (SEM) shows that micro structures of good quality and exhibited smooth surface, sub transparent and sub vitreous lustre. The FTIR studies was used to determine whether the bond structures were affected from the doping or not and revealed that the presence of O-H molecules and minute structural variations of synthesized materials.The TGA graph, temperature vs. weight % loss decreases with increasing the temperature shows Lithium strontium phosphateas thermally stable so it is used as some optoelectronic device applications.The electrical conductivity of LiSr2(PO4)3was investigated as a function of the nature of the transition-metal cation. Impedance measurement show that the materials have relatively good ionic conductance.
