However, both of these spectra contain emission lines that can't yet be matched with known electron transitions, limiting the information which can be gathered from them. In a study published in ...

A TECHNIQUE has been developed for observing monochromatic Cathodoluminescence from semiconductors in the scanning electron microscope ... the complete emission spectrum may be observed by ...

This means that each electron transition will produce a photon of a different frequency and hence a different colour. This causes line emission spectra to be produced, as shown below. This is not ...

An electron can be excited when its absorbs ... The emission of radiation can be analysed by an ‘emission spectrum’. The different coloured lines show the frequencies emitted by electrons ...

This creates vacancies, leading to a cascade of electron transitions within the atom as electrons from higher energy levels drop down to fill the vacancy. The energy released during these transitions ...
