A cataluminescence (CTL) sensor using Y2O3 nanoparticles as the sensing materials was proposed for the determination of ethyl acetate. This ethyl acetate sensor showed high sensitivity and specificity at the optimal temperature of 264°C. Quantitative analysis was performed at a wavelength of 425 nm. The linear ranges of CTL intensity vs ethyl acetate concentrations were 2.0–250 ppm (r = 0.9965) and...
A sensor for detecting dimethyl ether was designed based on the cataluminescence phenomenon when dimethyl ether vapors were passing through the surface of the ceramic heater. The proposed sensor showed high sensitivity and selectivity to dimethyl ether at an optimal temperature of 279°C. Quantitative analysis were performed at a wavelength of 425nm, the flow rate of carrier air is around 300mL/min...
The cataluminescence (CTL) of ether on nanosized ZnWO 4 was studied. A high sensitive and selective sensor for ether vapor was designed. Quantitative analysis was performed at an optimal temperature of 330°C, a wavelength of 425nm and a flow rate of 240mL/min. The linear ranges of CTL intensity versus concentration of ether was 20–3500ppm, with detection limit of 8.7ppm. The relative standard...
