Optical Properties of ZnSe Quantum Dots in Carbon Matrices

Abstract

У роботі синтезуються квантові точки ZnSe в матриці нанопористого вуглецю. Для цього синтезували нанопористий вуглець з необхідним розподілом розміру пор. З отриманих спектрів фотолюмінесценції було встановлено, що пік біля краю смуги в спектрі збудження може бути віднесений до найвищої ефективності передачі фотогенерованих носіїв у корельованих станах піддіапазону (приблизно на 34 меВ нижче зони провідності ZnSe) до стану глибокого центру. The ZnSe quantum dots in a matrix of nanoporous carbon are synthesized in the work. For this purpose, nanoporous carbon was synthesized with the required pore size distribution. From the received photoluminescence spectra, it was found that the peak near the band edge in the excitation spectrum can be assigned to the highest transfer efficiency of photogenerated carriers at the correlated sub-band states (about 34 meV below the conduction band of ZnSe) to the deep center states.
