The temperature-dependent and excitation-intensity-dependent photoluminescence(PL) spectra are applied to investigate the quateary (AlxGa1-x)0.51In0.49P(x = 0.29) alloys lattice-matched to GaAs. The PL peak is excitation intensity independent, but shows anomalous temperature behavior, where PL peak energy changes with temperature, exhibiting Z-shape dependence. The PL peak energy decreases with increasing temperaturefrom 19K, a blue-shift of PL peak energy occurs between 55K and 84K, afterwards, the PL peak energy de creases monotonously again. This confirms the existence of ordered structure caused by superlattice effect in the(Alx Ga1_x)0.51In0.49P(x = 0.29) alloys.
