Light sources are an indispensable component of an overwhelmingly large number of analytical methods. Radiometric characterisation of light sources in analytical chemistry is therefore of fundamental importance. This review presents up to date knowledge on methods to characterise radiometric properties of light sources in terms of radiometric power, irradiance, brightness, luminous efficacy, luminous efficiency and emission spectra, all of which are crucial parameters for their use in analytical chemistry. Special attention is paid to radiometric characterisation of new generations of light sources with focus on miniaturised and low-cost light sources suitable for portable analytical instrumentation. Miniaturised light sources, especially new generations of solid-state light sources including solution processable quantum dot light emitting diodes (QLEDs), organic LEDs (OLEDs) as well as conventional LEDs and lasers, are radiometrically characterised through various spectrophotometric, actinometric as well as new facile radiometric methods. Although the areas of analytical use of new light sources including QLEDs, OLEDs as well as other important light sources such as deep ultraviolet (DUV) and infrared LEDs in analytical chemistry are yet to reach their potential, their radiometric characterisation opens future options for their wider deployment in analytical chemistry.
