Title: Hot excitons are responsible for increasing photoluminescence blinking activity in single lead sulfide/cadmium sulfide nanocrystals

Abstract

The kinetics of PL blinking for isolated PbS/CdS nanocrystals changes with the photon excitation energy, with PL blinking increasing in frequency and changing from a two-state to a multistate on/off switching when the excitation energy changes from 1S_h–1S_e(≈1.4 eV) to 1P_h–1P_e(≈2.4 eV).

Excitation Intensity Dependence of Photoluminescence Blinking in CsPbBr₃ Perovskite Nanocrystals

Journal Article Gibson, Natalie A. ; Koscher, Brent A. ; Alivisatos, A. Paul ; ... - Journal of Physical Chemistry. C

Perovskite semiconductors have emerged as a promising class of materials for optoelectronic applications. Their favorable device performances can be partly justified by the defect tolerance that originates from their electronic structure. The effect of this inherent defect tolerance, namely the absence of deep trap states, on the photoluminescence (PL) of perovskite nanocrystals (NCs) is currently not well understood. The PL emission of NCs fluctuates in time according to power law kinetics (PL intermittency, or blinking), a phenomenon that has been explored over the past two decades in a vast array of nanocrystal (NC) materials.

Photoluminescence and electroluminescence in graded cadmium sulfoselenide electrodes: applications to photoelectrochemical cells

Journal Article Carpenter, M K ; Streckert, H H ; Ellis, A B - J. Solid State Chem.; (United States)

Inhomogeneous samples of n-type CdS/sub x/Se/sub 1-x/ (0 less than or equal to x < 1) were prepared by vapor-phase diffusion of S into a single-crystal CdSe substrate. Characterization of the samples by Auger electron spectroscopy (AES)/Ar ion sputter etching reveals that S has substituted for Se in the lattice to produce a graded region: The depth profile analysis indicates that from a composition with x nearly unity at the surface, x monotonically declines to zero over a distance of approx. 1 ..mu..m. Correspondingly, the band gap energy diminishes from approx. 2.4 eV for the CdS-like composition to approx. 1.7more »« less

Photoluminescent response of palladium-cadmium sulfide and palladium-graded cadmium sulfoselenide Schottky diodes to molecular hydrogen. Technical report

Technical Report Carpenter, M K ; Van Ryswyk, H ; Ellis, A B

The bulk photoluminescence (PL) of Schottky diodes constructed from Pd and n-type CdS (Pd-CdS) and from n-type, graded CdS/sub x/Se/sub 1-x/ (0 less than or equal to x less than or equal to 1; x - 1 at surface) (Pd-CdS/sub x/Se/sub 1-x/) is sensitive to molecular H/sub 2/. For the Pd-CdS diode, exposure to H2 (3:1, N/sub 2/:H/sub 2/ mixture) significantly enhances the PL intensity of edge emission lambda/sub max./approx. 510 nm) relative to the intensity in air; using a dead-layer model, the corresponding reductions in depletion width and Schottky barrier height can be estimated.

Luminescent photoelectrochemical cells. 4. Electroluminescent properties of undoped and tellurium-doped cadmium sulfide electrodes

Journal Article Streckert, H H ; Karas, B R ; Morano, D J ; ... - J. Phys. Chem.; (United States)

Single-crystal, n-type, undoped CdS and Te-doped CdS (100 and 1000 ppM CdS:Te) electrodes exhibit electroluminescence (EL) in aqueous alkaline peroxydisulfate electrolyte. Addition of Te to CdS introduces intraband gap states which drastically alter the EL spectral distribution. The EL spectrum of undoped CdS consists of a sharp band near the band gap energy (approx. 2.4 eV) with lambda/sub max/ approx. 510 nm and a weaker, broader band at lower energy; the EL spectra of 100 and 1000 ppM CdS:Te also exhibit a sharp band at approx. 510 nm but are dominated by broad bands with uncorrected lambda/sub max/ approx. 600more »« less
