In Fig. 6a, b the resulting blue fluorescence can be observed.

Unseen below was an area of some 2 square, km which was completely glazed over and giving off a weak steel blue fluorescence.

Grimpel produced a pea-sized lump of material which appeared to be surrounded by a cold blue fluorescence.

The paper will give a strong blue fluorescence if not filtered.

It is thought to attract prey by means of blue fluorescence.

The resulting material has a brilliant blue white fluorescence under short wave ultraviolet light.

Divalent europium is the source of the blue fluorescence, when seen in the mineral fluorite.

A faint trail of blue fluorescence glimmered in her wake.
