A Self-Referenced Refractive Index Sensor Based on Gold Nanoislands
We report on a self-referenced refractive index optical sensor based on Au nanoislands. The device consists of a random distribution of Au nanoislands formed by dewetting on a planar SiO<sub>2</sub>/metal Fabry–Pérot cavity. Experimental and theoretical studies of the reflectance of this...
