Fluorescence is light energy produced by a process where high-energy radiation (such as ultraviolet or X-ray) is absorbed by electrons surrounding an atom and is re-emitted as light energy.
Phosphoresence is light energy produced by a particular type of chemical reaction where the excess chemical energy of the reactants is given off as light energy.

The main difference between the two is the lasting power of the glowing. Phosphorescent materials glow for a longer period of time, and what's usually considered 'glow in the dark'. Fluorescent glows under blacklight, but this light does not remain at all afterwards.
It depends on what "stuff" you mean. Phosphorescence, fluorescence, luminescence, and incandescence are all possibilities.

The word phosphorescence is a material similar to fluorescence but it does not give out light quickly. It does this because it slowly absorbs radiation.
The difference between a spectrophotometer and a fluorometer is what they both measure. A spectrophotometer measures absorbance and a fluorometer measures fluorescence.

There are actually quite a few properties to classify rocks and minerals. Some of these are chemical composition, radioactivity, phosphorescence, grain size, hardness, color, streak and fluorescence.
