DESCRIPTION

BS ISO 23946:2020


This standard BS ISO 23946:2020 Fine ceramics (advanced ceramics, advanced technical ceramics). Test methods for optical properties of ceramic phosphors for white light-emitting diodes using a gonio-spectrofluorometer is classified in these ICS categories:
  • 81.060.30 Advanced ceramics

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.
