I just broke a lightbulb accidentally. I touched it, and it has a light-bluish substance inside, I washed my hands really really good, but I don't know what it is. I wish I knew what it was. Does anybody know? I got it on my bead and I want to know if it's leathal.

What is the composition of the phosphors used in fluorescent light bulbs?
The exact composition depends on the color type of the bulb, with the most common color types being cool white, warm white, deluxe cool white, and deluxe warm white. In each case, the phosphors are a mixture of crystals that may include: calcium halophosphate, calcium silicate, strontium magnesium phosphate, calcium strontium phosphate, and magnesium fluorogermanate. These crystals contain impurities that allow them to fluoresce visible light. These impurities include: antimony, manganese, tin, and lead.
