White light, white heat: A soft-chemistry synthesis of GeO, based on the thermally induced dehydration of Ge(OH)2, enables its thermal disproportionation to give size-controlled germanium nanocrystals (ncGe), which exhibit a pronounced size-dependent photothermal effect, superior to that of silicon nanocrystals (ncSi).
