Abstract：
 A luminescent gas-sensitive sensor based on nano material is composed of heater, ceramic substrate connected to said heater, nano material film applied on another surface of ceramic substrate, and quartz package with specimen inlet and outlet. A pull-up process for generating said nano material film includes proportionally mixing the nano material (TiO2, Cr2O3, SrCo3, etc) with its precursor or water, pulling up the ceramic heater from said mixture at 1-100 mm/min of speed, drying and sintering at 100-800 deg.C. Its advantages are high sensitivity, no loss, and long service life.
