Flashed phosphors absorb and accumulate an exciting emission (UV-, the emission of the visible spectrum range) and emit the recombination emission in the visible spectrum range as a bright and fast light flash when irradiated with a stimulated emission of IR spectrum that is, they convert an invisible IR emission into a visible light.
as a base for fluorescent paints;
as luminescent signs for marking devices, documents and other products;
as a luminescent component in the research.
High sensitivity of the phosphors to the IR-radiation with a low intensity in the wide spectral range.
