Tunable blue-shift of the charge-transfer photoluminescence in tetrapod-shaped CdTe/CdSe nanocrystals

open access: goldResults in Physics, 2021
The photoluminescence peculiarities and the excited state absorption of the tetrapod-shaped CdTe/CdSe nanocrystals are studied in the single-photon excitation regime.

White‐tailed Deer Signpost Photoluminescence [PDF]

open access: yesEcology and Evolution
Ultraviolet (UV) induced photoluminescence is widespread in Mammalia; however, its function(s) remain unclear. Most of the research to date has focused on the surface expression of photoluminescence (e.g., pelage), described qualitatively.

Glowing Green: A Quantitative Analysis of Photoluminescence in Six North American Bat Species [PDF]

open access: yesEcology and Evolution
Photoluminescence produced by excitation with ultraviolet light has been documented in an increasing number of nocturnal–crepuscular mammal species. Here, we provide a quantitative analysis to confirm visual observations of UV‐induced photoluminescence ...

Approaching the intrinsic photoluminescence linewidth in transition metal dichalcogenide monolayers [PDF]

open access: green, 2017
Excitonic states in monolayer transition metal dichalcogenides (TMDCs) have been the subject of extensive recent interest. Their intrinsic properties can, however, be obscured due to the influence of inhomogeneity in the external environment.

Understanding Transient Photoluminescence in Halide Perovskite Layer Stacks and Solar Cells [PDF]

open access: yesAdvanced Energy Materials, 2021
While transient photoluminescence (TPL) measurements are a very popular tool to monitor the charge‐carrier dynamics in the field of halide perovskite photovoltaics, interpretation of data obtained on multilayer samples is highly challenging due to the ...

Influence of Gold Nanoantennas on the Photoluminescence of Silicon Nanocrystals

open access: yesPhotonics, 2022
We study the influence of gold nanoantennas on the photoluminescence signal of silicon nanocrystals. Unlike bulk silicon, which only exhibits low photoluminescence at room temperature due to its indirect band gap, silicon nanocrystals have the advantage ...

Photoluminescence mechanism of carbon dots: triggering high-color-purity red fluorescence emission through edge amino protonation

open access: yesNature Communications, 2021
Due to complex structure and surface functionalities, photoluminescence mechanisms of Carbon Dots are unknown, and it is challenging to synthesize Carbon Dots to achieve the desired optical properties.
