Troubleshooting Measurements of Fluorescence Spectra

One of the most powerful techniques to understand the behaviour and performance of electrical devices is electroluminescence spectroscopy. In electroluminescence (EL) spectroscopy a working device, such as a light emitting diode or solar cell, is placed inside a spectrometer and the light emission properties of the device studied. EL spectroscopy can be performed as eith...

The inner filter effect is a common problem in fluorescence spectroscopy, affecting spectral measurements in particular. In this article we provide clear and practical steps to avoid the inner filter effect. View the article online. https://www.edinst.com/blog/inner-filter-effect/

In 1907 English engineer Henry Joseph Round was testing the rectifying current behaviour of SiC crystallites and noticed that a faint yellow light was emitted from the SiC; this was simultaneously the first reported observation of the phenomena of electroluminescence spectroscopy and the first successful operation of a light emitting diode (LED). The work of Round was ex...
