`"effecting conversion of the nanoparticle precursor into nanoparticles,"
`The method used to synthesize the Samsung Quantum Dots effects conversion of the nanoparticle precursor into
`nanoparticles.
`
`For example, upon information and belief, Samsung’s Quantum Dots are formed using the following synthesis
`process, which converts a nanoparticle precursor composition to a material of the nanoparticles:
`
`“We injected (TMS)3P at 150 °C in the presence of both indium laurate (In(LA)3) and zinc oleate (Zn(OA)2)
`
`precursors. At this mild temperature the In−P−Zn ligand complexes were first formed, and then they were
`
`converted to InP MSCs as the temperature increased to 170 °C, showing a sharp absorption peak at 370
`nm.”

`
`The conversion is effected under conditions permitting seeding and growth of nanoparticles. For example,
`Samsung’s Quantum Dots are formed using the following synthesis process:
`
`“During the InP synthesis, unlike the LaMer type growth, it has been known that the initial nucleation phase
`completely consumes the highly reactive P precursor such as (TMS)3P, and further growth takes place
`through the Ostwald ripening, which results in a large size distribution.”
`
`“We injected (TMS)3P at 150 °C in the presence of both indium laurate (In(LA)3) and zinc oleate (Zn(OA)2)
`
`precursors. At this mild temperature the In−P−Zn ligand complexes were first formed, and then they were
