| Outline of Final Research Achievements |
Integrated microchips detecting practical analytes such as environmental pollutants and biological samples are very useful. Usually, the detecting system in the microchip is based on the change of absorbance or fluorescence intensity using a small LED as a light source. We expect that light-emitting materials in solution by applying voltage are very useful instead of using LEDs because it is possible to change excitation wavelength easily by injecting different photoluminescent materials to the light emitting device. Here, we studied possibility of using light-emitting solutions as light source for the detection system on microchips. As candidates for the light emitting solution, thermally activated delayed-fluorescent molecules with high quantum yield of photoluminescence, and Eu and Tb complexes with narrow photoluminescence spectra were employed, and the light emitting characteristics were investigated. Moreover, narrowing emission spectra by edge emission was investigated.
