Two-photon absorption has been widely studied ... In 2PE you produce pairs of photons whose combined energy adds up to the electron-transition energy in the semiconductor. So by measuring the ...

Morphological characteristics were analyzed using transmission electron microscopy (TEM ... by increasing the surface area for photon absorption. TEM analysis showed contrasting shades, indicating ...

In addition, the material performs especially well with high levels of absorption in the infrared ... generation and ...

This work reports the design of an efficient multiband UC system based on Ln3+/Yb3+-doped core-shell upconversion ...

This energy is released as a photon. The energy of the photon can be worked out using the equation If an electron moves from level \(E_{2}\) to \(E_{1}\) the energy of the photon can be worked out ...
