Persistent Luminescent Materials

2016
Persistent luminescent materials have become an important class of multi-functional materials and have a broad application in many fields. The persistent luminescent materials have been mainly used as luminous materials. Besides, as for the photocatalysis, the persistent luminescent materials act as the light source for the photocatalysis in dark ...

IR-Luminescent Molecules in Hybrid Materials

Journal of Sol-Gel Science and Technology, 2003
In the present work we report on steady-state and dynamical optical properties of four polymethine dye molecules absorbing in the near infrared (IR) region (0.8–1.1 μm) and emitting around 1.2 μm. The molecules are embedded in organically modified silicate (ORMOSIL) material synthesized by a sol-gel method.

Recent Progress on Circularly Polarized Luminescent Materials for Organic Optoelectronic Devices

Advanced Optical Materials, 2018
Due to the characteristics of optical rotation, selective emission of polarized light, and circular dichroism, circularly polarized luminescent materials have aroused extensive attentions, and they have exhibited wide optoelectronic applications, such as

Fundamentals of Luminescent Materials

2017
Persistent luminescent materials feature long-lasting emission up to days after ceasing the excitation. In this chapter, the underlying mechanism of luminescence involving photon absorption, emission and afterglow processes is first described. We then place our emphasis on the discussion of emission features of inorganic persistent phosphors, including

Upconversion Luminescent Materials: Properties and Luminescence Mechanisms

2019
The upconversion (UC) luminescent materials typically refer to the materials doped with rare earth (RE) ions or transition metal ions as the luminescence centers, among which the lanthanides ions possess superior UC efficiency. UC luminescence (UCL) is a kind of anti-Stokes process, which absorbs two or more photons with a low energy while emits one ...

Properties of Luminescent Materials

Chemical & Engineering News Archive, 1942
WITH wartime conditions many military and some civilian operations must be performed undor materially reduced levels of illumination. The press has contained many references to loss of life and traffic snarls resulting from trial and real blackouts which, in turn, have created a widespread interest in the possibilities of luminescent materials.
