These techniques generally rely on pulsed high-intensity lasers and have better sample penetration than single-photon techniques. A visible stimulated Raman scattering microscope with extensive ...

The numerical results are validated by experimental LPB imaging outcomes of (1) a static two-photon polymerization (TPP) printed phase object measured in a lensless DIHM setup and (2) a dynamic sperm ...

Spontaneous emission is a phenomenon in which an excited atom falls to a lower-energy state and spontaneously emits a quantum of electromagnetic radiation in the form of a single photon. When a single ...

In light of this, they used an atomic force microscopy (AFM) tip to tap on some of their photon avalanching nanoparticles ... so we measured their emission while tapping on them.

With this in mind, they tapped on some of their photon avalanching nanoparticles (ANPs) with an atomic force microscopy (AFM ... so we measured their emission while tapping on them.

With this in mind, they tapped on some of their photon avalanching nanoparticles (ANPs) with an atomic force microscopy (AFM ... so we measured their emission while tapping on them.

In these particles, the absorption of a photon sets off a chain reaction that leads to the emission of many more ... with atomic force microscopy (AFP) tips, they noted that avalanching behavior ...

When they probed photon avalanching nanoparticles (ANPs) with atomic force microscopy (AFP ... leading to the emission of many photons. Image credit: pictafolio/iStock Using this knowledge ...
