A Ratiometric CdSe/ZnS Nanocrystal pH Sensor
Preston T. Snee,Rebecca C. Somers,Gautham Nair,John P. Zimmer,Moungi G. Bawendi,Daniel G. Nocera +5 more
TL;DR: The development of a reversible chemical sensor based on a CdSe/ZnS nanocrystal (NC) results in a ratiometric sensor since the emission intensities of dye and NC may be referenced to the isosbestic point between NC and dye emissions.
Journal ArticleDOI
Color‐Saturated Green‐Emitting QD‐LEDs
Jonathan S. Steckel,Preston T. Snee,Seth Coe-Sullivan,John P. Zimmer,Jonathan E. Halpert,Polina Anikeeva,Lee Ann Kim,Vladimir Bulovic,Moungi G. Bawendi +8 more
TL;DR: Although efficient green-emitting core–shell semiconductor NCs that emit at l= 525 nm have been synthesized, they have not been successfully incorporated into a QD-LED suitable for display applications, and herein, the synthesis of a (CdSe)ZnS core-shell material is reported.
Journal ArticleDOI
Whispering‐Gallery‐Mode Lasing from a Semiconductor Nanocrystal/Microsphere Resonator Composite
Journal ArticleDOI
Efficient emission from core/(doped) shell nanoparticles: applications for chemical sensing.
TL;DR: In this article, a simple two-step synthesis can be used to create these nontoxic materials that display efficient energy transfer from the core to the Mn doped shell, which opens the possibility of using these materials as bioimaging agents.
Journal ArticleDOI
Blue semiconductor nanocrystal laser
Yinthai Chan,Jonathan S. Steckel,Preston T. Snee,J.-Michel Caruge,Justin M. Hodgkiss,Daniel G. Nocera,Moungi G. Bawendi +6 more
TL;DR: In this paper, the authors demonstrate tunable room-temperature amplified spontaneous emission and lasing from blue-emitting core-shell CdS∕ZnS nanocrystals (NCs) stabilized in a sol-gel derived silica matrix.
