The paper reports a strong modification of the emission properties of a rhodamine monolayer bonded to the surface of a 1DSi1−xNx:H PhC. The photoluminescence signal observed at 670 nm is enhanced by more than 1 order of magnitude at the angle where the emitters are evanescently coupled to a Bloch surface wave supported by the structure. These results may be important for the design of efficient light-emitting devices and of optical sensors.

Abstract
The paper reports a strong modification of the emission properties of a rhodamine monolayer bonded to the surface of a 1DSi1−xNx:H PhC. The photoluminescence signal observed at 670 nm is enhanced by more than 1 order of magnitude at the angle where the emitters are evanescently coupled to a Bloch surface wave supported by the structure. These results may be important for the design of efficient light-emitting devices and of optical sensors.File in questo prodotto:
