Improving the near-infrared luminescence of Ca3MgSnGe3O12:Cr3+ using cation modulation and energy transfer for night-vision and nondestructive testing
{{output}}
A series of Ca3Mg1-x Sr x SnGe3O12:0.05Cr3+ (x = 0.005-0.3) phosphors were synthesized in this study; varying the Cr3+-ion crystal-field strength through Sr2+-concentration variation resulted in a luminescence-center redshift. Nd3+-ion co-doping resulted in a ... ...
