Red to Blue Excitonic Emission with Ultra-Thin Quantum Wells and Fractional Monolayer Quantum Dots of II-VI Semiconductors
نویسندگان
چکیده
Ultra-thin quantum wells of CdTe and CdSe and fractional monolayer quantum dots of CdSe present very strong excitonic emission covering the red-blue spectral range. They are grown by atomic layer epitaxy and the thickness fluctuations can be completely avoided in many cases by choosing the appropriate substrate temperature. These systems appear as promising candidates for the elaboration of red to blue light emission devices.

In this work, we have studied the miniband and minigaps of GaN/AlN constant total effective radius multi-shells quantum dots (CTER-MSQDs) and Rings (CTERMSQRs).We have investigated effects of the Hydrogenic donor impurities, quantum dots and rings radii, and the number of wells on miniband formation by sub-band energy calculations. We show that in these systems, minigaps can be created and then...
متن کاملInGaN µLEDs integrated onto colloidal quantum dot functionalized ultra-thin glass.
Red-, orange-, and green-emitting integrated optoelectronic sources are demonstrated by transfer printing blue InGaN µLEDs onto ultra-thin glass platforms functionally enhanced with II-VI colloidal quantum dots (CQDs). The forward optical power conversion efficiency of these heterogeneously integrated devices is, respectively, 9%, 15%, and 14% for a blue light absorption over 95%. The sources a...

Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...
متن کاملSynthesis and Optical Study of CdZnTe Quantum Dots
The comparison of growth processes and fluorescent properties of CdZnTe semiconductor quantum dots that are synthesized in different concentrations of Zn2+ in water are discussed in this paper. The samples are characterized through absorbtion (UV) and photoluminescence spectra (PL). The results show that when the reaction time is prolonged, the absorption peak and fluorescent emission peak pres...
