摘要

The ZnSnTe2O6 nanocomposite is synthesized by hydrothermal process. It exhibits an intriguing shape of rectangular bar. The average particle size, energy band gap, and refractive index are 152.7 nm, 5.86 eV, and 1.642, respectively. Strong UV, green, and red emissions are obtained by luminescence emission spectrum. UV emission is due to radiative hole-electron recombination, qualifies the sample for display devices. The visible emission peaks are ascribed to various Schotty and Frenkel surface defects, as well as oxygen interstitials. The sample is diamagnetic at 300 K and 5 K. Thermal study shows the endothermic reaction insighting the heat absorption by the sample confirming sample melting. The exothermic reaction absence or heat release confirms the crystallization absence in the sample. And, 13.09% mass loss is observed over 800 °C temperature, with the first order derivative curve. XPS confirms of chemical state of the sample and assures the orbital state of an element with spin-orbit coupling (j). Electrochemical analysis exhibits pseudo-capacitive behavior with potential window 0.8 V and specific capacitance is 140.30 F/g.
