IR luminescence of CaGa2O4: Yb3+ excited by 940 and 980 nm radiation

Existing calcium gallate CaGa O, based luminescent materials radiating in visible IR region have been reviewed. IR luminophores have been studied but slightly but their practical implementation is of interest. CaGa O, specimens activated with Yb rare-earth ions have been synthesized using the solid-...
