Room temperature operable solid-state sensors for selective methanol vapour detection from orthorhombic WO3 nanoplates

Synthesis of Pr3+-doped WO3 particles: correlation between photoluminescent and photocatalytic properties

“…It is possible to identify bands at 270 and 325 cm −1 that correspond to the exion vibration modes of the d(O-W-O) connections. 35,36 The characteristic bands at 712 and 801 cm −1 are characteristics of WO 3 of the monoclinic phase and associated with the n(W-O-W) connections lengthening mode. 35,37 Vibrational modes at low frequencies, as you can see at 129 cm −1 , are associated with lattice modes.…”

Tailored mesoporous γ-WO3 nanoplates: unraveling their potential for highly sensitive NH3 detection and efficient photocatalysis

“…21,22 For the secure monitoring of dangerous gases at room temperature, low-temperature detection methods are preferred. 23 The gas sensing capabilities of metal oxide semiconductors are influenced by the physical and chemical properties of a substrate via thick film technology. The rough surface substrate has a substantial impact on its gas sensing capabilities; numerous researchers have shown that substrates with a rough surface are better for gas sensing capabilities.…”

Humidity Sensing Mechanism and Respiration Monitoring of WO3 Nanoplates with a Monoclinic Crystal Phase

“…Typically, the WO 3 has a lemon yellow color while the colour of WO 2 is blue and brown. 5 The most attractive applications of tungsten oxide nanomaterials include electrochromic, 6 sensors 7,8 and photochromic. 9 Tungsten oxide is a rare oxide for visible-light-active photocatalysis in a single phase.…”
