Sample Concentration Affects Optical Gain Results in Colloidal Nanomaterials: Circumventing the Distortions by Below Band Gap Excitation Gabriel Nagamine ...

The color change is quite rapid, and seems to also result in a general increase in the LED’s intensity, although that could be an optical illusion; our eyes are most sensitive in the greenish ...

The role of the nitrogen doping on the optical, structural, and photocatalytic properties of ZrO 2-x N x films was investigated. UV-Vis-NIR spectroscopy was employed to investigate the optical ...

This review presents the basic physical principles of optical band gaps, their band gap tunability, potentials, and limitations in the applications for the water treatment. Furthermore, it reports ...

The Gap Band’s Charlie Wilson discusses hit song's connection to 1921 Tulsa massacre Some have said their hit song "You Dropped a Bomb on Me" is about the massacre.

It is desirable to develop high-performance infrared devices using non-toxic, direct transition semiconductors with a band gap in the infrared range.

It is very clear from this research report that both refractive index and optical band gap-based-oxide ion polarizability and optical basicity have the same decreasing trend as the temperature is ...
