Spectroscopic studies of metastable tetragonal ZrO nanocrystals.

This study delves into an examination of the structural and luminescent properties of zirconium dioxide (ZrO) synthesized via the solid-state combustion method. Nitrates are harnessed as the oxidizing agent, while glycine serves as the fuel. Two distinct compositions are explored: a stoichiometric 1:1 ratio and a fuel-enriched 1:2 ratio.

Electronic structure and defect-induced luminescence study of phase-stabilized t-ZrO nanocrystals.

Luminescent tetragonal-ZrO (t-ZrO ) nanocrystals were synthesized using an optimized combustion method without post-synthesis annealing and characterized using X-ray diffraction, electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, UV-Vis. spectroscopy, photoluminescence spectroscopy, thermoluminescence (TL), and vibrating sample magnetometry. The as-synthesized t-ZrO nanocrystals have a bandgap of 4.
