Colored emitters with silica-embedded perovskite nanocrystals for efficient daytime radiative cooling

, 2021
Daytime radiative cooling is an innovative way to counter the temperature increase caused by solar exposure inside buildings, cars, and industries without consuming energy. To improve the radiative cooling performance, the light-to-heat energy conversion

Functional electrospray emitters

The Analyst, 2009
Electrospray ionisation (ESI) is a soft technique used in mass spectrometry (MS) analysis able to introduce a wide variety of analytes in the gas phase. Briefly, it consists in the application of a high-voltage to a solution to spray it through a small orifice.

Asymmetric Blue Multiresonance TADF Emitters with a Narrow Emission Band.

ACS Applied Materials and Interfaces, 2021
In this study, we synthesized and characterized multiple resonance (MR) type blue thermally activated delayed fluorescence (TADF) emitters. Unlike many boron-based MR-TADF materials, the blue TADF emitters of this work had an asymmetric molecular ...

Slice emittance and projected emittance

Chinese Physics B, 2008
This paper presents an analytical description for the growth of the projected emittance (here just referred to the transverse emittance) based on the concept of the slice emittance in an RF photoinjector. In the RF photoinjector, the slice emittance undergoes small changes, but the projected emittance changes significantly even in the drift space after

Tunnel emitter

Proceedings of the 26th Annual International Conference on Mobile Computing and Networking, 2020
Backscatter enables transmissions at orders of magnitude lower energy consumption when compared to conventional radio transmitters. Backscatter tags achieve this by the reflection or absorption of carrier signal generated from emitter devices. However, backscatter systems are limited by these emitter devices, as they are significantly energy-expensive ...

Strain‐Induced Modification of the Optical Characteristics of Quantum Emitters in Hexagonal Boron Nitride

Advances in Materials, 2020
Quantum emitters in hexagonal boron nitride (hBN) are promising building blocks for the realization of integrated quantum photonic systems. However, their spectral inhomogeneity currently limits their potential applications.
