<P>SrZn2(PO4)(2) doped with Eu3+ ions was prepared by high temperature solid-state reaction. The site-selective excitation and emission spectroscopy and luminescence decay (lifetime) have been investigated in the D-5(0)-> F-7(0) region by using a pulsed, tunable, and narrowband dye laser. We observed two crystallographic sites for Eu3+ in SrZn2(PO4)(2) below 250 K and energy transfer from Eu3+ at one site to Eu3+ at the other site. The Stark energy levels of Eu3+ at two different sites were assigned from the site-selective emission spectra. The luminescence from Eu3+ at one of the two sites was quenched at room temperature. The lifetime of Eu3+ ions at the two sites is compared. The defect structures and charge compensation mechanisms are discussed.</P>
