Single Crystal Growth and Crystal Structure Analysis of Novel Orange-Red Emission Pure Nitride CaAlSiN:Eu Phosphor.

Single crystal of novel orange-red emission CaAlSiN:Eu phosphor was grown by our original vapor phase technique, and the precise crystal structure was investigated for the first time by single crystal X-ray diffraction analysis. The crystal structure of CaAlSiN:Eu single crystal was verified to be an α-SiN-type trigonal structure (space group 31) with = 0.79525(9) nm, = 0.
