    A series of Eu3+ doped BaLa2ZnO5 was prepared by a Pechini-type solgel method. The effect of Eu3+ concentration on the structure and the luminescent properties of the samples BaLa2-xEuxZnO5 were investigated by powder X-ray diffraction (XRD) and photoluminescence (PL) spectra. The sample adopts the tetragonal or orthorhombic structure as the Eu3+ concentration reaches below 1.2 or over 1.6, respectively. The sample is a mixture of tetragonal and orthorhombic phases as the contents of dopants lie between 1.2 and 1.6. The phosphor offers the strongest red light as content of Eu 3+ is 0.4. In addition, the crystallization processes of the complex precursors were examined by simultaneous thermogravimetry and differential thermal analysis (TGDTA), and also the optimal heating temperature was investigated.
