ZnO thin films have been deposited on Si (111) substrate by ultrasonic spray pyrolysis (USP) with various growth temperatures. The polycrystalline of ZnO thin films have preferred plane (002) and ...

Nanoparticles’ environment, in particular pH, can strongly affect their photoluminescence (PL). This can be especially true for the surface PL of nanodiamonds (NDs) known to be dependent on the ...

Searching more solid materials with efficient phonon-assisted photoluminescence up-conversion is important to enrich optical refrigeration research. Here, we demonstrate the phonon-assisted PL ...

Underpinning all this progress is the work of Hiroshi Amano and his colleagues, who made a pivotal breakthrough in GaN ...

Scientists across the world are working to make quantum technologies viable at scale—an achievement that requires a reliable ...

Multi-resonant Au/Si particles exhibit unique photoluminescence spectra, enabling creation of physical unclonable functions with sub-diffraction-limited critical sizes.

Operation is simple. Just load the sample into the sample chamber. Then enter a few conditions on the measurement software to measure the fluorescence lifetime and photoluminescence (PL) spectrum.

Abstract: All PV modules must maintain their performance for years once deployed in the field. Understanding the impact of new processing and materials on the long-term reliability of panels is thus ...
