Excitonic structures in the electrophotoluminescence spectra of KI

Экситонная структура в злектрофотолюми несцентных спектрах KI

  • Published:
Il Nuovo Cimento B (1965-1970)

Summary

The RT excitation spectra of photo- and electrophoto-luminescence obtained on KI crystals forhv >E g are reported and discussed. It is shown that the structures observed in both spectra can be explained in terms of exciton decay into the continuum.

Riassunto

Nel presente lavoro sono riportati e discussi gli spettri di foto- ed elettrofoto-luminescenza ottenuti su cristalli di KI illuminati a temperatura ambiente con fotonihv >E g . Si mostra come tali spettri di eccitazione possano essere spiegati facendo ricorso al processo di decadimento nel continuo di alcuni eccitoni.

Реэюме

Приводятся и обсуждаются RТ спектры воэбуждения фото- и злектрофотолюмин есценции, полученные на кристаллах КI дляhv<E g . Покаэывается, что структуры, наблюденные в обоих спектрах могут быть общяснены в терминах распада зкситона в континиум.
