polymer light-emitting diode
polymer light-emitting diode[¦päl·ə·mər ‚līt·i‚mid·iŋ ′dī‚ōd]
An organic polymeric material that emits light in response to the application of an electric field. It may be an organic semiconductor sandwiched between metals of high and low work functions or a heterostructure made of two polymers, which increases the likelihood of radiative electron-hole recombination because of the energy-band structure. Also known as light-emitting polymer; polyLED.
