This paper reports the photoluminescence spectral properties of Eu3+, Tb3+, Dy3+ and Ho3+ doped LaOX, YOX, (La, Gd)OX, and (La, Y)OX (X=F, Cl) powder phosphors. Under the UV-light these phosphors have exhibited bright reddish-orange, green, yellowish-blue and bluish-green colours. This papers also describes the effects of the halides change in the host material chosen specifically.
