This work reports the design of an efficient multiband UC system based on Ln3+/Yb3+-doped core-shell upconversion nanoparticles (Ln/Yb-UCNPs, Ln3+=Ho3+, Er3+, Tm3+). In the design, Ln³⁺ ions are ...

The technology is based on two-photon absorption; when the beam of an ultrafast ... fabricated using electron-beam lithography and evaporation of metal films. So far, the fabrication of high ...

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

They have found a new use for the superconducting nanowire photon detectors (SNSPDs ... work by absorbing individual photons. The absorption generates small electrical changes in the ...

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 ...
