Luminescent property of Eu3+ in a new compound, (Sr0.99La1.01)Zn0.99O3.495

The luminescent property of Eu3+ in (Sr0.99La1.01)Zn0.99O3.495 solid solution was systematically examined. (Sr0.99La1.01)Zn0.99O3.495 was newly found in the Sr-La-Zn-O system. Under ultraviolet excitation, emission intensity increases with increasing Eu3+ concentration to y = 0.7 in (Sr0.99La1.01(1-y)Euy)Zn0.99O(3.495-0.015y) solid solution. The crystal system of the solid solution changed from tetragonal (y=0.1similar to0.4) to orthorhombic (y=0.5similar to0.7). (C) 2002 The Electrochemical Society.
