Synthesis, Structure and Luminescence Characterization of Erbium Doped Hydroxyapatite Nanoparticles by Precipitation Method | Bentham Science

摘要

Introduction: Hydroxyapatite, Ca10 (PO4)6(OH)2, a ceramic material is the majorinorganic component in bones and teeth of animals and humans. Although erbium is one ofthe prominent representative elements among the lanthanides, erbium doped hydroxyapatitehas not been studied to a greater extent. This study reports the synthesis of erbiumdoped hydroxyapatite using the simple precipitation method and its structural and opticalproperties.Objectives: The primary objective of this study was to synthesize erbium doped hydroxyapatiteand to study the structural and optical properties.Materials and Methods: Nanocrystalline erbium doped hydroxyapatite was successfullyprepared using simple precipitation method. Average particle size of the synthesized particlewas around 8-10 nm.Results: The typical absorption spectra of the erbium doped hydroxyapatite sample showsalmost well defined peaks of the erbium ions. The absorption bands were observed at 360nm, 373 nm, 448 nm, 490 nm, 524 nm and at 653 nm. The photoluminescence spectrumshowed the presence of a green band at 550 nm and a red band which peaked at 750 nm.Conclusion: Spherical shaped nanocrystalline hydroxyapatite, Ca10 (PO4)6(OH)2 substitutedwith Erbium(III) were obtained using precipitation method. The synthesized Er3+ dopedhydroxyapatite can be used for biophotonic applications, which exploits their exquisite opticalproperties and infrared imaging and several other therapeutic applications.
