IN connexion with investigations now in progress on some hydrides in the third group in the periodic system, I have studied the spectrum of indium hydride. The bands were obtained in the emission ...

For example, gallium nitride emits ultraviolet light, but adding indium shifts the emission across the visible spectrum and into the infrared. The emission can be controlled further by sandwiching ...

since its spectrum produced a brilliant indigo line. To look at with the naked eye though, indium is actually silvery-white and shiny. As you might have guessed from what we mentioned above about ...

The varying Indium concentration results in a spatially 600 varying band gap, which changes the local emission spectrum of the diode. Figure 2 illustrates a microscope image of a blue LED at low ...

while adding indium shifts emission to longer wavelengths through the visible spectrum. However, for a number of reasons, pushing emission as far as red by adding a lot of indium is problematic.
