(a) Time-resolved DAP PL decay of Ga₂O₃ NCs containing different amounts of surface-bound TGA without CdSe/CdS NCs. TGA equivalents and absolute concentrations (in parentheses) in Ga₂O₃ NC suspensions are indicated in the graph (aqua blue trace (0.84 mM) represents TGA concentration for the highest acceptor to donor ratio); (b) Time-resolved DAP PL decay of Ga₂O₃ NCs in the NC conjugates having different CdSe/CdS to Ga₂O₃ NC concentration ratio, as indicated in the graph; (c) Quenching efficiency of the DAP PL of Ga₂O₃ NCs in the NC conjugate (squares) and with bound TGA (triangles).
