A magnetic luminescent hybrid nanoparticle Fe3O4/BaMoO4:Dy3+ (MLHNP) was successfully synthesized by the co-precipitation method using ethylene glycol.

This book presents the abstracts of the papers presented to the Online National Conference on Research and Developments in Material Processing, Modelling and Characterization 2020 (RDMPMC-2020) held on 26th and 27th August 2020 organized by the Department of Metallurgical and Materials Science in Association with the Department of Production and Industrial Engineering, National Institute of Technology Jamshedpur, Jharkhand, India.

Fe3O4@LaF3:Eu,Ag hybrid magnetic luminescent nanoparticles (NPs) were synthesized using a simple co-precipitation method and then functionalized with β-cyclodextrin (β-CD) using (3-aminopropyl)triethoxysilane (APTES). The chemical composition, crystalline nature, particle size, and surface morphology of the Fe3O4@LaF3:Eu,Ag@APTES@β-CD NPs were investigated, using powder X-ray diffraction, and high-resolution transmission electron microscopy. The uptake and release profiling of the LaF3:Eu,Ag@Fe3O4@β-CD NPs for the hydrophilic drug ciprofloxacin, showed 40 and 85% efficiency, respectively. The results indicated that the NPs have a high drug loading yield and a sustained drug releasing profile of the NPs, indicating that they can be used as a drug carrier. The photoluminescence spectral analysis of the NPs revealed their potentiality for use in bioimaging. Further analysis of the drug-loaded NPs (Fe3O4@LaF3:Eu,Ag@APTES@β-CD-ciprofloxacin) revealed, 100% microbial inhibition efficiency against Escherichia coli and Vibrio cholerae, and a minimum of 80% against Bacillus cereus.
