Prevalent Room-Temperature Phosphorescence in Natural Nuts

Journal of the American Chemical Society
Room-temperature phosphorescence (RTP) has extensive applications in various fields such as data encryption, chemical sensing, optoelectronic displaying, and time-resolved bioimaging, yet most materials are fossil fuel-based. Recently, an increasing interest has emerged with respect to natural organic RTP.

Solid-Surface Room Temperature Phosphorescence

Applied Spectroscopy Reviews, 1992
Abstract Luminescence can be defined as radiation emitted from atoms or molecules as they undergo a radiative transition from an excited state to a lower energy state. After the absorption of incident radiation, the emission of a photon during the radiative transition is called photoluminescence.

Room temperature phosphorescence optosensing for gadolinium

Mikrochimica Acta, 1997
An optosensing method for gadolinium based on the room-temperature phosphorescence behavior in aqueous solution induced by the transient adsorption of the complex formed by 1,4-bis (1′-phenyl-3′-methyl-5′-pyrazolone-4′-)butanedione (1,4) with Gd (III) on the chelating resin Chelex 100 (packed in a flow cell) is proposed.

Micelle Stabilized Room Temperature Phosphorescence

1982
Micelle stabilized room temperature phosphorescence (MS-RTP) is reported for a representative variety of functionally-substituted aromatic compounds dissolved in aqueous solutions of sodium lauryl sulfate detergent containing 30% thallium(I) counter-ions.

Development of a Room-Temperature Phosphorescence Fiber-Optic Sensor

Analytical Chemistry, 1996
The design of a new fiber-optic sensor based on solid-surface room-temperature phosphorimetry is presented for the analyses of polycyclic aromatic hydrocarbons in water samples. Analytical figures of merit are given for several compounds of environmental importance.

AIEgen with Fluorescence–Phosphorescence Dual Mechanoluminescence at Room Temperature

Angewandte Chemie, 2016
AbstractWe report the first example of an AIEgen (DPP‐BO) with fluorescence–phosphorescence dual emission under mechanical stimulation. By carefully analyzing the crystal structure of DPP‐BO, the efficient intermolecular and intramolecular interactions should account for its unique mechanoluminescence (ML) properties, especially the abnormal ...

Waterborne Polyurethanes with Tunable Fluorescence and Room-Temperature Phosphorescence

ACS Applied Materials & Interfaces, 2015
Single-component materials with both fluorescence and room-temperature phosphorescence (RTP) are useful for ratiometric sensing and imaging applications. On the basis of a general design principle, an amino-substituted benzophenone is covalently incorporated into waterborne polyurethanes (WPU) and results in fluorescence and RTP single-component dual ...

ON THE ROOM TEMPERATURE PHOSPHORESCENCE OF WOOL KERATIN

Photochemistry and Photobiology, 1978
Abstract—A study has been made of the room‐temperature phosphorescence behaviour of wool keratin and its major constituent proteins. The 290 nm induced phosphorescence of wool, previously thought to decay by second‐order kinetics, is shown to consist of two separate components which decay exponentially with lifetimes of 0.18 × 0.03 and 1.45 × 0.25 s ...
