Abstract
Monoclinic La1-xCexOHSO4 compounds (0 less than or equal tox less than or e qual to1) were hydrothermally synthesized from mixed rare earth nitrates an d thiourea at moderate temperature. The crystals grown are all flake-like i n morphology and display room temperature ultraviolet luminescence. The mea n dimension of the crystals turns smaller, and the luminescent intensity tu rns stronger following the increase of cerium content in the phosphor compo unds. (C) 2001 Elsevier Science B.V.
