  2. Potassium fluorosilicate - Wikipedia

    en.wikipedia.org/wiki/Potassium_fluorosilicate

    Potassium fluorosilicate is a chemical compound with the chemical formula K 2 [SiF 6].. When doped with potassium hexafluoromanganate(IV) (K 2 [MnF 6], with Mn 4+) it forms a narrow band red producing phosphor, (often abbreviated PSF or KSF), of economic interest due to its applicability in LED lighting and displays.
