Abstract

II-VI semiconductor nanostructures are particularly interesting due to their potential applications in novel optoelectronic devices. There have been many advances in the field, but relatively little work has been done on II-VI semiconductor low-dimensional systems under non-resonant laser radiation. Although the potential outcomes may be important for designing tunable optical devices, they involve complicated numerical techniques. Dealing with nano-scale problems frequently implies tricky mathematical issues as the non-analytical solutions. In this paper we investigate the effects of the laser field radiation on the electronic subband levels in cylindrical CdS/SiO₂ quantum dots. Understanding the laser effects on the oscillator strength for the intraband transitions in CdS/SiO₂ quantum dots may be relevant in the quantitative interpretation of the future experimental data related to this kind of structures. Our results prove that laser radiation could be used for tuning the quantum dots optical absorption/emission.
