ABSTRACT:
A phosphor tape article includes a phosphor layer having a phosphor and a polymeric binder material, a pressure sensitive adhesive layer disposed adjacent the phosphor layer such that light transmitted through the pressure sensitive adhesive layer is received by the phosphor layer, and a release liner disposed on the pressure sensitive adhesive layer. The pressure sensitive adhesive layer is disposed between the release liner and the phosphor layer. The phosphor is suitable for excitation by UV or blue LED light, and the phosphor emission has a characteristic decay rate of less than 1 second. Light emitting devices including pieces of phosphor tape, and methods of making such devices, are also disclosed.
