Fine ceramics (advanced ceramics, advanced technical ceramics) — Test methods for optical properties of ceramic phosphors for white light-emitting diodes using a gonio-spectrofluorometer
Preview
Summary
This document specifies a method for use of a gonio-spectrofluorometer to measure internal quantum
efficiency, external quantum efficiency, absorptance, luminescent radiance factor and relative
fluorescence spectrum of ceramic phosphor powders which are used in white light-emitting diodes
(LEDs) and emit visible light when excited by UV or blue light.
