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.

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.

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 ...

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 ...

Solid-Surface Room Temperature Phosphorescence

2020
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 in Crystalline Iodinated Eumelanin Monomer

Chemistry – A European Journal
AbstractWe report the room temperature phosphorescence upon iodination on a crystalline eumelanin monomer with shielded hydroxyl moieties, ethyl 5,6‐dimethoxyindole‐2‐carboxylate (DMICE). Ultrafast intersystem crossing (ISC) is observed in the iodinated (IDMICE) as well as brominated (BDMICE) analogues of the eumelanin monomer derivative in solution ...

Triarylmethanol Derivatives with Ultralong Organic Room‐Temperature Phosphorescence

Chemistry – A European Journal
AbstractTriphenylmethyl‐based compounds such as rhodamines and fluoresceine representing an old and well‐known class of triphenylmethane dyes, are widely used in fluorescent labeling of bioimaging. Inspired by ultralong room temperature phosphorescence of triphenylphosphine derivatives, herein we report a methoxy substituted triarylmethanol ((4 ...

Enhancing the Room-Temperature Phosphorescence Performance by Salinization of Guests

The Journal of Physical Chemistry Letters
Although the host-guest doped strategy effectively improves the phosphorescence performance of materials and greatly enriches the variety of materials, most of the guests are organic molecules with weak luminescence ability, which leads to the need for further improvement in the phosphorescence performance of doped materials. Herein, by salinization of
