ABSTRACT:
A detection method and indicator are disclosed that includes quantum dots that fluoresce under illumination of a first light having a first wavelength to indicate the presence of a predetermined condition, and in particular, a corrosion condition. The quantum dots are surrounded by a shell material that under normal conditions reflect the first light and reacts in the presence of the predetermined condition to permit the first light to illuminate the quantum dot to excite the quantum dot to emit a second light having a second wavelength, which when detected, indicates the presence of the predetermined condition.
