Revisiting two thiophosphate compounds constituting d0transition metal HfP2S6and d10transition metal α-Ag4P2S6as multifunctional materials for combining second harmonic generation response and photocurrent response

A new multifunctional material α-Ag 4 P 2 S 6 , which combines moderate photocurrent response and second harmonic generation coefficients, can be grown as mm-sized crystals with salt flux AgBr.
