The Compact Fluorescent Lamp (CFL) contains several elements.


Mercury-vapor in the tube

Silicon-solid in the diodes

Aluminium-in the base

Argon-in the tube

Tungsten-in the filaments

Copper-circuit board wires


Barium oxide-coating the filaments

Strontium oxide-coating the filaments

Yttrium oxide-in the phosphor

Lanthanum phosphate-in the phosphor

Europium oxide-phosphor dopant

Terbium phosphate-phosphor dopant

Cerium phosphate-phosphor dopant

Silicon dioxide-circuit board construction

Sodium calcium silicate-glass tube


It is recommended to collect a different substance for each element. For example, do not have a neodymium magnet represent nickel (from the plating), neodymium, iron, and boron. You will have a bor(on)ing element collection that way.
