- W2079101849 abstract "Photoluminescence spectra of the hexagonal layered semiconductor PbI2 have been measured at 4.2°K on various single crystalline specimens. They are interpreted in relation with the anisotropic polariton model. The emitted radiation is assumed to originate from free and bound exciton recombination, with and without phonon emission. A peak polarized E ∥ c about 4 meV above the excitonic line is related to the extraordinary polariton mode. Le semiconducteur PbI2 à structure cristalline lamellaire de symétrie hexagonale produit des spectres de photoluminescence mesurés à 4,2°K et qui sont interprétés en relation avec le modèle des polaritons dans les cristaux anisotropes. La radiation émise provient de la recombinaison d'excitons libre, respectivement lié, avec et sans émission de phonons. Un pic polariséE ∥ c situé 4meV au-dessus de la ligne excitonique se rapporte au mode polaritonique extraordinaire." @default.
