Isomorphism of Sr[Li₃AlO₄] and Sr[Li₃GaO₄] - Syntheses, Crystal Structure, and Europium(II) Luminescence.

ABSTRACT: While highly efficient red-emitting inorganic phosphors have been discovered in the substance class of alkaline earth oxo(nitrido)lithoaluminates, new narrow-band green- and yellow-emitting components are being sought to improve the performance of phosphor-converted light-emitting diodes (pc-LEDs). Various solid-state reactions were carried out under protective gas atmosphere in nickel crucibles and sealed tantalum ampules to synthesize Sr[Li₃AlO₄], Sr[Li₃GaO₄], and five substitutional derivates of Sr[Li₃(Al_1-x Ga _x )O₄] at moderate temperatures. The observation of a linear increase in the unit cell parameters as a function of the increasing gallium mole fraction x in Sr[Li₃
