Abstract

Pyrophosphates are very useful as bioactive ceramics; particularly, calcium pyrophosphate has made impressive progress as biocompatible material promoting tissue formation. 2% Mg, 5% Mg, and 10% Mg ion doped SrPPi nano-particles are synthesized using a surfactant-mediated approach. The Powder XRD pattern confirms the tetragonal structure of materials and nano-structured in nature. The transmission Electron Microscopy (TEM) study confirmed the nano-size and the dimensions in the range from 7.46 nm to 51.70 nm. P-O-P and PO3 have both symmetric and asymmetric stretching vibrations, according to the FT-IR spectroscopy investigation. The direct optical energy band gap for 2% Mg, 5% Mg, and 10% Mg ion doped Sr2P2O7 samples is found to be 4.98 eV, 4.75 eV, and 4.55 eV using UV-NIR absorption spectroscopy, spanning the spectral range of 210–1200 nm. EDAX analysis confirmed the elemental presence. Thermogravimetric analysis proved that the sample included water molecules. According to TGA, the samples become anhydrous and almost remain stable when heated over 600 °C–1000 °C. Photoluminescence studies indicate the emission is in the visible range. BET analysis gives information on surface area and pore size.
