Abstract
A system and method for detecting and quantifying the concentration of rare earth elements in a fluid contacting a sensor, the method having the steps of: providing the sensor to an environment such that the sensor is in contact with the fluid, wherein the sensor features a fiber extending between a first end and a second end along a longitudinal axis, wherein the sensor further features a coating on the second end of the fiber, and wherein the coating is a metal-organic framework material including, but not limited to zinc adeninate, 1,3,5-benzenetricarboxylate, 4,4-biphenyldicarboxylate, and combinations thereof; interrogating the sensor with light; collecting a luminescent signal; and detecting the rare earth elements in the fluid contacting the sensor using the luminescent signal.
