The glare source used in the study was generated by a Xenon bulb which has relatively greater energy contributed from longer wavelength than shorter, but was basically white light containing energy across the 400 700 nm region.
"White light, white light," he mulled.
The Si-NC sample was probed with a super continuum white light with photon energies ranging between 2.75 and 1.26 eV.
However, unlike the degenerate measurement, probing was carried out using a super continuum white light with photon energies ranging between 1.26 and 2.75 eV. Figure 3a c shows the normalized transient absorption measurements for three different photon excitation energies, namely at 4.13, 3.5, and 3.09 eV, respectively.
As one steps inside the building, the eye goes first to the central staircase, which is lit from below by bright white light — a bolt of energy that zigzags up the big open atrium to the glass rooftop, where steel ribs, which support louvres that close when the sun gets too bright, embody more of the arabesques that Hadid's pen traced on paper eleven years earlier.
Combining the contribution of adjusting Ho3+ concentration and pump power, near equal energy white light was obtained.
The nanocrystals emit the near equal energy white light with high brightness and favorable color balance when excited using a 980 nm continuous wave diode laser.
First, the TiO2/CdS/CdSe co-sensitized structure extended the absorption range to long wavelength of white light, which adequately utilized the light energy.
The UV excitation of the complex in the solid state generates white light emission which indicates significant energy transfer from the ligands (acetylacetone and pyrazines) to the Dy III) ion.
White is from analogy to white light, which has roughly equal energy at all visible frequencies, and pink stems from the fact that light with a fractal distribution appears pink, with strongest components at the long-wavelength (red) end of the chromatic spectrum.
