In present study, a temperature field of specimens which was coated with fluorescence dye such as Rhodamine-B(Rh-B) has been measured, based on the fluorescence intensity. Silica(SiO2) nano porous structure with 1um thickness was constructed on a cover glass, and fluorescence dye was digested into these porous thin films. To optimize manufacturing coating process, various solvents, Rh-B concentration, and other chemical materials were applied to fabricate the specimen and all specimens were measured on the various temperature conditions. For the measurement, a 14 bit cooled CCD camera with 1600 by 1200 spatial resolution is equipped with epifluorescence microscope to obtain only fluorescence intensity from 1.2 ㎜ by 0.9 ㎜ field of view of the illuminated coated specimen.

As the target size of measurement objects lessened to the micro-scale, it is impossible to apply the classical contact methods into temperature measurements. Recently, the LIF technique using fluorescence dye has been used in many research fields to measure temperature. In this study, the specimens with the nano-sized porous thin films are manufactured by injecting fluorescence solution into the glass plate. The optimized manufacturing conditions are determined by the analysis of all parameters that influence to the emission intensity and the experiments are carried out with the specimens produced in the optimized conditions. Then, the deviations of the fluorescence intensity are measured at several different temperatures, and the visualizations of the temperature field are performed by taking intensity distributions from the specimen at various temperature fields.
