Fluorescent liquid penetrants and methods of nondestructive testing |
| abstract |
A fluorescent liquid penetrant is provided which includes a liquid medium having a plurality of fluorophores disposed therein. Upon excitation with a suitable light source, the penetrant exhibits a quantum yield greater than 40% (or in some embodiments, greater than 90%). In some embodiments, the fluorophore is a low-toxicity quantum dot. In some embodiments, the fluorophore has significantly reduced self-absorption, which allows for surface discontinuity depth measurement. Also disclosed are apparatuses for using these fluorescent liquid penetrants for non-destructive testing purposes. In some embodiments, these tests include measuring the depth of a discontinuity by analyzing photoluminescence intensity and/or photoluminescence peak position shift. |
