title: Overcoming crystallographically imposed geometrical restrictions on the valence state of Eu in CaGdAlO4: realization of white light emission from singly-doped Eu phosphors.
abstract: We demonstrate a strategy to manipulate the valence state of Eu in CaGdAlO4 based on breaking down geometrical restrictions on the activators. This strategy could promote the search for novel phosphors for white light emission diodes (WLEDs).
