Stretching the Limits of Refractometric Sensing in Water Using Whispering-Gallery-Mode Resonators
A novel application of microresonators for refractometric sensing in aqueous media is presented. To carry out this approach, microspheres of different materials and sizes were fabricated and doped with Nd<sup>3+</sup> ions. Under 532 nm excitation, the microspheres presented typical NIR...
