The calculated results reveal that the different substituted ligands can modify the absorption and emission properties.
Indeed, the layer of silicon can act as a Fabry-Pérot interferometer [36], which modifies the absorption properties of the substrate.
On gradually increasing the CB input power, the carrier concentration within the cavity increases which modifies the absorption and the refractive index of the saturable absorber.
It should be remarked that the c-a transition in Si QDs embedded in SiO2 actually modifies the absorption by lowering the optical bandgap of about 0.4 eV [10].
Annealing at 600°C does not significantly modify the absorption of Ge QDs, while the change of α at 800°C is inferred to the presence of crystalline QDs (evidenced by TEM already at 750°C).
On the basis of this, attempts to modify the absorption range, improve specific capacitance and lower resistance to acquire effective photo-current responses have been successfully demonstrated in this research.
The latter occurs due to the change in the imaginary part of the refractive index, iαλ/4π, which modifies the absorption coefficient through free carrier absorption while the former occurs due to change in the real part of the refractive index through free carrier change of index (Δn) of the Si.
However, skin viability did not significantly modify the absorption rate of BPA.
Indeed, in addition to the two tetrapyrrole pigments avian eggshells consist of numerous other compounds that may selectively absorb light or modify the absorption properties of the two pigments.
Factors that might influence the risk of lead toxicity in adults include preexisting disease affecting relevant target organs (e.g., hypertension, renal disease, or neurologic dysfunction), nutritional deficiencies that modify the absorption or distribution of lead (e.g., low dietary calcium or iron deficiency), advanced age, and genetic susceptibility.
