title: Intrinsic chromatic switching of visible luminescence in Yb3+,Er3+:CsCdBr3.
abstract: Bistability is reported in sensitized Er3+ luminescence driven by an Yb3+ transition that previously revealed an Yb3+ luminescent instability. To our knowledge this is the first report of bistable energy transfer between different rare-earth ions.
