A to Z L is for Luminescence

#AtoZChallenge 2019 Tenth Anniversary blogging from A to Z challenge letter

Happy Saturday hard to believe we are officially half way through the challenge
Sorry that I got behind ( had a lot of life dumped into my lap the last 2 weeks)
could use continued prayers.

L is for Luminescence  emission of light by a substance that hasn't been heated as in fluorescence and phosphorescence   this is not my photo today!  could not find one of my own.
