heal.abstract	Undoped, as well as Ce3+ and Cr3+ doped LiSrAlF6 (LiSAF) crystals have been examined by Raman spectroscopy in order to identify the-system's molecular vibrations and the role of doping. Furthermore the electron spin resonance (ESR) spectroscopic technique has been used to study the distortions of the local crystalline environment of Ce. The analysis of the main ESR resonance shows that the Ce3+ ions substitute for Sr2+ ones in the structure and permit the description of the electronic eigenfunctions and energy splitting of its F-2(5/2) ground state. We have tackled, the distortion of the trigonal crystalline environment, induced by Na+ codopants acting as charge compensators to Ce3+, and we have assigned the ESR resonances to Na occupying sites at various distances from the Cc atoms. Our results indicate growth of high quality crystals. (C) 2003 American Institute of Physics.	en
