Nanosized γ-Al2O3 + Nd2O3-based cataluminescence sensor for ethylene dichloride
A gas‐sensor utilizing cataluminescence (CTL) on nanosized γ‐Al2O3 + Nd2O3 for measuring low concentrations of gaseous ethylene dichloride (EDC) was developed. The results showed that γ‐Al2O3 nanoparticles as a catalyst offered high sensitivity and selectivity in the detection of EDC. The addition o...

| description | A gas‐sensor utilizing cataluminescence (CTL) on nanosized γ‐Al2O3 + Nd2O3 for measuring low concentrations of gaseous ethylene dichloride (EDC) was developed. The results showed that γ‐Al2O3 nanoparticles as a catalyst offered high sensitivity and selectivity in the detection of EDC. The addition of a small quantity of Nd2O3 increased the intensity of CTL more than two‐fold. Quantitative analysis was performed at a wavelength of 400 nm and at an optimal temperature of 279°C, and the optimal flow rate of carrier gas was 320 mL[sol ]min. Under the optimized conditions, the linear range of CTL intensity vs. concentration is 6–5000 ppm (R = 0.9996; n = 7), with a detection limit of 2 ppm. The response time is |
