Photon Statistics from Yb3+-Doped CsPbCl3 are Inconsistent with Quantum Cutting
Vincent R. M. Benning, Faris Horani, Daniel R. Gamelin +1
CsPb(Cl1-xBrx)3:Yb3+ has been widely reported as a broadband quantum-cutting material with a photoluminescence quantum yield exceeding 100%, making it a promising candidate for enh…
Quantifying the Distribution of Biexciton Emission Efficiencies in Colloidal Quantum Shells
Tjom Arens, Dulanjan Harankahage, Divesh Nazar +2
The efficiency of multi-photon emission is an important characteristic of quantum light sources. Bright multi-photon emission is desirable for high-power lighting and lasers, while…
Vanishing quantum confinement enables bright and thermally excited multi-carrier emission from semiconductor nanocrystals
Tjom Arens, Sander J. W. Vonk, A. Willem Vlasblom +5
Recently, nanocrystals in the regime of vanishing quantum confinement-termed bulk nanocrystals (BNCs)-have demonstrated remarkable optical gain characteristics. While their high-po…
Controlling viscosity to engineer focal conic domains in photonic cellulose nanocrystal films
Diogo V. Saraiva, Lotte Polling, Ivo R. Vermaire +3
Cellulose nanocrystals (CNCs) form cholesteric architectures that can have color specific reflectivity and enable sustainable photonic films. However, achieving uniform color, supp…
Hot-carrier trapping preserves high quantum yields but limits optical gain in InP-based quantum dots
Sander J. W. Vonk, P. Tim Prins, Tong Wang +10
Indium phosphide is the leading material for commercial applications of colloidal quantum dots. To date, however, the community has failed to achieve successful operation under str…
