    摘要: A system for displaying luminescence comprises a crystalline structure comprising a compound having the formula:.alpha.-CuAlX.sub.4wherein the compound has lattice parameters a=b ranging from 5.430(1) .ANG. to 5.751(3) .ANG.; c ranging from 10.069(1) .ANG. to 10.570(4) .ANG.; and X is selected from the group consisting of chlorine, bromine, and a mixture thereof. The crystalline structure may also include a compound of the formula:.beta.-CUAlCl.sub.4wherein the compound has lattice parameters a=7.635(2) .ANG., b=12.842(2) .ANG., and c=6.127(1) .ANG.. The system also includes an excitation source which transmits energy to the crystalline structure such that the crystalline structure displays luminescence. The crystalline structure is also useful in a gas sensor application since the luminescence of the crystalline structure is capable of being quenched in the presence of gaseous material.
