    • Such featureless absorption spectra are often reported for indirect-bandgap semiconductor nanocrystals such as Ge (see references [4a] and [4b, In conventional transmission spectrometers, there is considerable dampening of the absorption structures in the absorption/extinction spectrum due to contributions from scattering as well as absorption.[13] A refinement of the Ge(0) NC absorption spectrum with photothermal deflection spectroscopy[13] would yield an excitation spectrum of the nonradiative recombinations of photoexcited carrier pairs, thus allowing a more precise excitation wavelength to be chosen for irradiation

    • The fact that repetitive and sustained temperatures were observed would seem to indicate that there is minimal surface oxidation (due to photochemical and/or thermal surface reactions) during the NIR radiation timeframe. Significant oxidation would decrease the photothermal output,[13b] and could eventually release GeO2 into the surrounding environment
