Photochemical electronic doping of colloidal CdSe nanocrystals.
A method for electronic doping of colloidal CdSe nanocrystals (NCs) is reported. Anaerobic photoexcitation of CdSe NCs in the presence of a borohydride hole quencher, Li[Et3BH], yields colloidal n-type CdSe NCs possessing extra conduction-band electrons compensated by cations deposited by the hydride hole quencher. The photodoped NCs possess excellent optical quality and display the key spectro...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولStudy of quantum size effects and optical characteristics in colloidal Cd1-xSnxTe quantum dotes
In this work, we report, optical properties of Cd1-xSnxTe quantum dots (x= 0.05, 0.10 and 0.15) synthesized in water using thioglycolic acid (TGA) as a modifier agent. The optical characterization of the samples was performed through absorption (UV) and photoluminescence spectra (PL). A red shift absorption and fluorescent emission peaks was observed which can be related t...

متن کاملThe Optical Properties of CdSe Quantum Dot-Bithiophene Complexes
We studied the optical and electrochemical properties of four model oligomers M3, M5, M9 and M17, Fig. 1. We have performed extensive experimental and theoretical analyses of the M series oligomers in order to determine the oligomers that would be the best charge transfer partners for CdSe quantum dots with respect to spectral overlap and band level alignment. The steady-state absorption and fl...
