“…Moreover, the deposition techniques were more affordable in comparison with more techniques such as doping of SnO 2 by copper 106 and combined zirconium-palladium. 107 The proposed gas sensor of Ratcheva et al, 106 which was designed based on copper-dopped SnO 2 film, acts through strong bond formation between phosphorus and copper and oxidation of PH 3 by surface-located ionized oxygen. As a possibility, the hydrogen can react with oxygen leading to the mendacious increase of conductivity.…”

Metal phosphides, especially aluminum phosphide, and phosphine (PH 3 ) are widely used as insecticides and rodenticides for protection of grains during process of storage and transportation. The main reason of poisoning with this compound is related to the conscious ingestion of salts or accidental inhalation of PH 3 . So the early and accurate diagnosis of poisoning can significantly help to the effective clinical treatment or recognition of death cause. PH 3 is somewhat unstable due to reaction with oxygen or hemoglobin leading to formation of oxy-acids phosphorous. Here, we critically reviewed the literature introducing the quantitative and qualitative methods for the detection of metal phosphides, PH 3 , and its products. This study obviously demonstrates that during past years, different diagnosis methods have been remarkably progressed. Head-space gas chromatography and confirmatory colorimetric methods have been as the most popular techniques. Also, the gas sensors are a promising method that must be more progressed.

“…At present, special research interest has been expressed in polycrystalline semiconductor materials consisting of nanometersized crystals whose structural and electrical properties are governed by a number of quantum-confinement effects [9][10][11][12]. It is important to note that the sensitivity, selectivity, and stability of chemical sensors based on semiconductor oxides can be improved by doping with different metals [13][14][15][16][17][18] and metal oxides [19][20][21][22][23].…”

An anomalous change in the electrical conductivity near the phase transition temperature (343 K) is revealed in a PbSe + PbSeO 3 two-phase polycrystalline composite. It is demonstrated that the observed effect can be used in the design of chemical gas sensors, in which the chemisorption of a reducing or oxidizing gas on the surface of the PbSe + PbSeO 3 composite should lead to a significant change in the electrical conductivity at temperatures close to the phase transition point. The PbSe + PbSeO 3 composite is studied by impedance spectroscopy in the temperature range 293-393 K in a dry air atmosphere. It is found that the interaction of the sample with air oxygen under the controlled joint action of an ac electric field and heat can lead to both reversible and irreversible changes in the electrical conductivity.

“…Metal oxide semiconductors have been used to detect small concentrations of oxidizing, reducing and combustible gases in air. Materials have been grown with sensitivity to: H 2 [42,46,47], , O 3 [51][52][53], H 2 S [54][55][56][57], NO x [58][59][60], PH 3 [61], NH 3 [62][63][64], CH 4 [65][66][67], ethanol [68][69][70][71][72] and LPG [73][74][75]. In the majority of the devices, the detection mechanism of these gases requires oxygen in the atmosphere and is influenced by the presence of water vapors.…”
