Single crystal method of manufacture of MTiOAsO4, single domain crystals and crystalline than to become composition MTiOAsO4 of MTiOAsO4

摘要

Doped crystalline compositions (e.g., single domain crystals) of MTiOAsO4 (wherein M is K, Rb and/or Cs) are disclosed which contain at least about 10 ppm total of Fe, Sc and/or In dopant. Also disclosed is a flux process which is characterized by adding said dopant to a melt containing the components for forming MTiOAsO4, in an amount effective to provide a doped single domain crystal of MTiOAsO4 containing at least 10 ppm of said dopant.
