From Cs8Sb4Nb5O5F35 to Cs6Sb4Mo3O5F26: The first noncentrosymmetric fluoroantimonite with d0 transition metal

The first noncentrosymmetric d 0 TM fluoroantimonate, Cs 6 Sb 4 Mo 3 O 5 F 26 , has been achieved by substituting the d 0 TM in centrosymmetric Cs 8 Sb 4 Nb 5 O 5 F 35 . Cs6Sb4Mo3O5F26 features a phase-matchable SHG response of about 72% of the commercial KDP. Its powder laser-induced damage threshold (133.5 ​MW/cm 2 ) is about 33.4 times that of AGS (4.0 ​MW/cm 2 ).
