Outline of Final Research Achievements

Optical gas sensing properties of optical nanocomposite materials composed of semiconductor nanoparticles (quantum dots) were investigated. It has been demonstrated that core-shell quantum dots composed of CdSe-based core and ZnS-base shell show reversible change in photoluminescence intensity by exposure to ozone in air at room temperature under atmospheric pressure. Red-emitting quantum dots with relatively large particle size were suitable for the detection of ozone over a wide range of concentrations (1-500 ppm). Green-emitting quantum dots with smaller particle size showed high sensitivity to low concentration ozone down to 0.1 ppm. The QDs responded to gaseous alkylamines with lower sensitivity than the sensitivity to ozone. These results clearly show that photoluminescent quantum dots have considerable potential for use as optical sensor materials for the detection of hazardous gases.
