摘要：
We have analyzed the surface morphology of single crystal samples of lead diiodide and studied the absorption edge and the temperature variation of their photoluminescence spectra. We have established that the zirconium impurity is uniformly incorporated into the crystal lattice of the samples and promotes appreciable quenching of photoluminescence due to formation of electron traps. © 2007 Springer Science+Business Media, Inc.
