This is upconverting photons in energy... which requires energy, unlike fluorescence (which downconverts). There's nothing in the article to suggest how these contacts perform this miracle of energy creation, nor even how much of the IR spectrum is involved.
Oh, and it's "Chinese researchers". So... grain of salt. Many are legit, but bunkum is regularly published there.
