Fluorescent is the correct spelling, while flourescent is a common misspelling. The word fluorescent describes something that emits light through fluorescence or has an exceptionally bright, vivid color.
For example, “She wore a fluorescent yellow jacket that was easy to see from a distance.”
The main difference is the order of the letters near the beginning. Fluorescent starts with fluo, while flourescent incorrectly changes that sequence to flou.
