Title
(EN) NEAR INFRA-RED COMPOSITE POLYMER-NANOCRYSTAL MATERIALS AND ELECTRO-OPTICAL DEVICES PRODUCED THEREFROM

Abstract
(EN)
The invention comprises a composite material comprising a host material in which are incorporated semiconductor nanocrystals. The host material is light-transmissive and/or light-emissive and is electrical charge-transporting thus permitting electrical charge transport to the core of the nanocrystals. The semiconductor nanocrystals emit and/or absorb light in the near infrared spectral range. The nanocrystals cause the composite material to emit/absorb energy in the near infrared (NIR) spectral range, and/or to have a modified dielectric constant, compared to the host material. The invention further comprises electro-optical devices composed of this composite material and a method of producing them. Specifically described are light emitting diodes that emit light in the NIR and photodetectors that absorb light in the same region.
(FR)
L'invention concerne une matière composite comprenant une matière hôte dans laquelle sont incorporés des nanocristaux semi-conducteurs. La matière hôte est une matière émettant ou transmettant la lumière et transportant des charges électriques, ce qui permet le transport des charges électriques jusqu'au noyau des nanocristaux. Les nanocristaux semi-conducteurs émettent et/ou absorbent la lumière dans la gamme d'infrarouge proche. Ils font en sorte que la matière composite absorbe ou émette de l'énergie dans la gamme d'infrarouge proche et/ou possède une constante diélectrique modifiée par rapport à la matière hôte. L'invention concerne également des dispositifs électro-optiques fabriqués à partir de cette matière composite et un procédé de fabrication correspondant. Elle concerne plus particulièrement des diodes lumineuses qui émettent de la lumière en infrarouge proche et des photodétecteurs qui absorbent la lumière dans la même gamme.
