Optical and structural characteristics of NQDs synthesized using new P precursors. (a) Absorption and PL spectra of InP synthesized using P(SiMe2-tert-Bu)3. (b) Emission from InP/ZnS core-shell NQDs with a PL max of 535 nm (green line), 573 nm (blue line), and 625 nm (red line). (c) Electron micrograph of InP NQDs (d = 2.14 nm (σ = 0.38), 1s max = 560 nm). (d) Size of synthesized InP obtained from electron micrograph with respect to the first excitonic transition.
