Abstract
The YFeO3 (12 h, 24 h, 48 h and 72 h) microcrystals were prepared by hydrothermal process. Structural characterization using X-ray diffraction confirms the orthorhombic perovskite of the synthesized materials. YFeO3 based gas sensor has good selectivity to formaldehyde. The response value of YFeO3 (72 h) sensor is up to 318 for 100 ppm formaldehyde at room temperature. Furthermore, YFeO3 has an ultra-fast response-recovery time of about 6.3 s/0.9 s and exhibits excellent cycle repeatability and stability. This trait can play significant practical role in kind of sensors with real-time detectability. Further SEM and XPS analysis suggest that enhanced sensing property can be related to the uniform hierarchical structure and high oxygen vacancies. Our research indicates that adjusting the experimental approach can alter the structural and sensing properties of the sample.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
