UP CONVERSION pour visualiser le rayonnement infrarouge
Up-Conversion is a very unusual phenomenon.
A counter-intuitive anti-stokes process occurs where the material absorbs lower
energy photons and emits higher energy photons as fluorescence. The trick
is that up-conversion materials absorb two or more low energy photons and then
emit one high energy photon. By definition, up-conversion phosphors must
be much less efficient than down-conversion phosphors. Typically,
up-conversion phosphors are illuminated with high intensity light sources such
as lasers in a controlled (subdued) lighting environment.
phosphor is suitable for various kinds of printing application, and will not
have any worse effect while mixing with any types of inks. It's can be added in
plastic, paper, cloth, ceramic, glass and solution etc. Laser pen or home
appliance controller are selected to test this phosphor material.
