    • The diffraction pattern obtained from a Lorentzian-based convolution did not show a resemblance to the experimental diffraction spectrum because of the better separation of the original peaks.

    • note
    • This fact is associated with a lower affinity of this powder to the adhesive tape, which results in an incomplete coverage. Alternatively, it can reflect some surface contamination. Note that the extra carbon amount is too large to be related to the metal attenuation associated with the particle core.

    • note
    • Various unpublished experiments have shown the preference of lead binding to glass. Since the matrix dissolution was performed in a glass apparatus, we postulate that lead is partially bound to the glass, thus changing the Pb/Cd ratio, leaving a higher percentage of cadmium in the NPs.

    • note
    • The ratios of alcoholic solution vs. aqueous solution were taken in such a way as to assure no precipitation occurred when mixing the hydrocarbon-methanol solution with pure water. Thus, we ensured that when replacing water with the aqueous salt solution, only precipitation of the hydrocarbon salt would occur, and we thus avoided to have the pure hydrocarbon as a by-product.

    • Capping is necessary to avoid Ostwald ripening and to retain the size of the NPs.
