Anti-Stokes
Phosphors are developed for up-conversion of long-wave IR-radiation
(1,5-1,6 um) into that short-wave (0,8-1,02 um) and radiation of IR-range
0,9-1,07 um into visible light of various colours. They are useful
in night viewing devices for spectral sensitivity broadening of electron-optical
image converters (up to 1,6 um), in light-emitting diodes (LED) of
various types, for visualization of IR-radiation and laser adjustment,
as well as for marking of documents and value papers.
The Phosphors of ASP-group are powders, consisting of
rare earth activated compounds based on yttrium (and some other elements)
oxides, fluorides, oxysulphides, and oxychlorldes.
The offered phosphors provide parameters stability of
emitters during > 100000 hours and within temperature range of
-60°C +70°C.
