  • Is luminous powder the same as phosphor (fluorescent pigment)?

    Is luminous powder the same as phosphor (fluorescent pigment)?   Noctilucent powder is called fluorescent powder, because when it is luminous, it is not particularly bright, on the contrary, it is particularly soft, so it is called fluorescent powder. But there is another type of phosphor in the ...
