以下摘自与Maxim的联络邮件： By the way, probably you know that powder pattern is much better than single crystal diffraction especially for doping level proving. This is because cell volume from PXRD has 10 times smaller esd than SXRD. Bragg-Brentano is much better than Debay diffraction.
Mn 2+ and Mn 4+ ions are known to be the most efficient activators, 1,2 but the Mn 3+ ion is not an efficient activator in any host, with the exception of garnets. 3,4 摘引自Mn-activated Na2SiF6 red and yellowish-green phosphors: A comparative study. Journal of Appl ...
