The Effect of Defects on Inorganic Academic Article uri icon

abstract

  • The most basic analysis of wide-band crystals doped with luminescent ions assumes that 1) the ions enter in the fixed (desired) valence state, 2) the sites exhibit the expected symmetries and 3) the dopant ions do not interact with each other. However, many interesting effects occur due to the violation of the above assumptions. The most recent Cr": YAG infrared laser is based on chromiium ions being forced into the+ 4 valence state in a+ 3 ionic site [1]. Energy transfer between neodymium and chromium is a crucial step in the …
