The surface plasmon polaritons that occur on the metallic grating surface were excited by a He-Ne laser of 633 nm wavelength. The effect of the grating was investigated by angle-resolved reflection and emission spectroscopy performed on the thin film samples with and without the grating. Incident light of both s-and p-polarizations were considered in this experiment and the measurement was performed in the reflection and the photoluminescence modes as well. The results exhibit remarkable resonant effect of photoluminescence enhancement over those observed from the sample with planar silver coating for both incident light polarizations. The much larger enhancement factor of ∼50.0 found for the case of p-polarized light can be attributed to the combined contributions of surface plasmon polariton enhanced absorption of excitation light and the resonant coupling between the SPP and the fluorophore, while only the latter was operating in the case of s-polarized incident light which showed a smaller enhancement factor of 6.0. © 2012 World Scientific Publishing Company.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]oxazine,photoluminescence enhancement,sinusoidal grating,Surface plasmon polariton[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work was supported by Osaka University Global COE “Center for Electronic Devices Innovation” Program.
