What is Photoluminescence Lifetime?

Why is my sample glowing? It's a great question, and at Edinburgh Instruments we can help you measure the lifetime of its glow! Photoluminescence- (fluorescence and phosphorescence) are processes where a molecule absorbs a specific wavelength of light, is excited, and re-emits it at a different, lower energy. The wavelengths in question, and the amount of time your molecule stays in the excited state can tell you about its electronic structure and help you identify and improve your processes!
