| Outline of Final Research Achievements |
Due to the leakage problem of gas-H2, we have changed our target from condensed phase hydrogen to a surface localized polariton which can be generated by the strong interaction of the Bloch surface wave and organic exciton. We have prepared a periodic oxide thin-film layer to prepare a Bloch surface wave. The transfer matrix simulation is performed using SiO2 and Ta2O5 layer as a target medium. We have fabricated the designed structure using a magnetron sputter, and checked its structure by cross section SEM image. The total reflection type microscope setup is built using a high-NA objective lens. We have measured the k-space image of the reflected light to observe the angle-dependent reflectivity spectrum. We have successfully measured the reflected image from the periodic oxide thin-film layer, and detected a dip on the reflectivity. The mismatch between the simulation and experiment is not negligible, which may be due to the low quality (homogeneity) of our sputtered sample.
