Synthesis of NPLs with exceptional thermal stability using BBN-EH. (a) Scheme for ZnSe NPLs synthesis using (BBN)₂Se/BBN-EH chemistry. Addition of aniline generates BBN-SeH in situ and produces thermostable ZnSe NPLs. (b) Pure BBN-SeH and (c) BBN-TeH fail to induce NPL formation. (d) Without BBN-SeH, the formed NPLs are unstable, rapidly degrading and disappearing at 120 °C. (e) Absorption spectrum of ZnSe NPLs prepared by conventional protocol. (f) Presence of BBN-SeH renders ZnSe NPLs highly thermostable. (g) Addition of c-LBs does not induce surface-limited conversion due to vertical growth inhibition in NPLs (black and red). Addition of 10% BBN-TeH to (BBN)₂Se produces thermostable 345 nm ZnSe NPLs.
