Self-assembly structured Sm2O3 nanomaterials were prepared by a simple and cost effective hydrothermal method and subsequent annealing at 800 °C in air. The size, shape and phase composition of the structures synthesized by changing the hydrothermal processing time were characterized by SEM-EDX, XRD, micro-Raman and photoluminescence (PL) analysis. Differences in particle aggregation and coalescence were reported upon varying the timing of hydrothermal process (from 24 to 36h). Sensors performances of the synthesized Sm2O3 nanostructures have been investigated for the monitoring of two important volatile organic compounds (VOCs) such as ethanol and acetone.

Abstract
Self-assembly structured Sm2O3 nanomaterials were prepared by a simple and cost effective hydrothermal method and subsequent annealing at 800 °C in air. The size, shape and phase composition of the structures synthesized by changing the hydrothermal processing time were characterized by SEM-EDX, XRD, micro-Raman and photoluminescence (PL) analysis. Differences in particle aggregation and coalescence were reported upon varying the timing of hydrothermal process (from 24 to 36h). Sensors performances of the synthesized Sm2O3 nanostructures have been investigated for the monitoring of two important volatile organic compounds (VOCs) such as ethanol and acetone.Pubblicazioni consigliate
