Electrical and Optical Properties of NdAlO3 Synthesized by an Optimized Combustion Process

Nanocrystals of neodymium aluminate (NdAlO3) are synthesized using an optimized single step auto-ignition citrate complex combustion process. The combustion product was characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy a...
