This　paper　reports　the　synthesis　of　neodymium　substituted　bismuth　titanate　nanoparticles　(BNdT)　for　ferroelectric　random　access　memory　(FeRAM)　based　applications　using　sol-gel　route.　X-ray　diffraction　pattern　showed　that　the　BNdT　nanoparticles　exhibited　perovskite　structure　with　orthorhombic　phase.　The　microstructure　of　the　BNdT　nanoparticles　showed　that　the　grains　were　in　spherical　structure　with　a　bi-modal　distribution　of　spheres.　Dielectric　constant　and　dielectric　loss　of　BNdT　nanoparticles　were　measured　in　the　frequency　range　100 Hz　to　100kHz.　Nd-substituted　BNdT　nanoparticles　showed　the　high　remanent　polarization　(Pr=33.2 μC/cm2,　Ec=62.5 kV/cm)　than　pure　bismuth　titanate　(BT)　(Pr=14.6 μC/cm2,　Ec=182.8 kV/cm)　ideal　for　FeRAM　based　applications.　The　occurrence　of　red　shift　in　photoluminescence　(PL)　spectrum　is　considered　to　be　due　to　the　isomerisation　that　may　occur　from　the　heating　of　samples.　©　2017　Chinese　Materials　Research　Society
