    CdTe nanocrystals studied through in-situ electro-modulation spectroscopy
    (Видавництво Львівської політехніки, 2012) Ince, R.; Patan Alper, F. M.; Yükselici, M. H.; Asıkoğlu, A.; Allahverdi, Ç.
    Non-linear optical properties of weakly confined CdTe nanocrystals in a glass matrix were studied by electro-modulation spectroscopy. Copper electrodes of about 10 nm thick were deposited on both sides of glass samples of thickness 0.8 mm by physical vapor deposition. Optical transmission spectra of the samples were recorded under dc high voltage applied to the electrodes. The absorption band is observed to broaden. This is most likely caused by state filling.
