Figure 5

Experimental results of high-resolution RI sensing. Sample concentration increased stepwise from 0.00 EtOH% to 1.00 EtOH%. (a) Relation between the sample RI, or ethanol concentration, and the angle-fixed SPR reflectance (RSPR). (b) Relation between the sample RI, or ethanol concentration, and the SPR reflectance angle (θSPR).
