Europium(III) diphenylphosphinate as a potential low-dimensional nanostructured coordination polymer scintillator

open access: yesMaterials Letters: X, 2023
Rare earth diphenylphosphinates – [RE(dpp)3]n – are low-dimensional nanostructured luminescent materials with considerable thermal and chemical stability, obtained in powder form, consisting of highly insoluble nanowire/nanorod-shaped particles.

Preparation and Properties of Rare-earth-doped Na2Ca3Si2O8 and BaZrSi3O9 Matrix Luminescent Materials

open access: yesChemical Engineering Transactions, 2018
To achieve higher quality temperature measurement, this paper studies the rare-earth-doped Na2Ca3Si2O8 and BaZrSi3O9 matrix luminescent materials. The paper mainly adopts sol-gel method to prepare luminescent material in the form of thin film and powder.

Rational design for thermochromic luminescence in amorphous polystyrene films with bis‐o‐carborane‐substituted enhanced conjugated molecule having aggregation‐induced luminochromism

open access: yesAggregate, 2021
We designed the triad molecule, bis‐o‐carborane‐substituted bis(thienylethynyl)benzene, as a filler for realizing thermochromic luminescent behaviors based on conventional polymer films, such as polystyrene.

Flexible and Transparent Luminescent Cellulose-Transition Metal Cluster Composites

open access: yesNanomaterials, 2023
Red-NIR luminescent polymers are principally obtained from petroleum-based derivatives in which emitters, usually a critical raw material such as rare-earth or platinum group metal ions, are embedded.

Spatially-resolved measurement of optically stimulated luminescence and time-resolved luminescence [PDF]

open access: yesRadiation Measurements, 2003
Spatially-resolved measurements of optically stimulated luminescence (OSL) were performed using a two-dimensional scanning system designed for use with planar samples. The scanning system employs a focused laser beam to stimulate a selected area of the sample, which is moved under the beam by a motorised stage.

Quantitative Determination of Luminescent Coupling in Multijunction Solar Cells from Spectral Photovoltage Measurements [PDF]

open access: yes, 2016
We present a simple method to quantify the magnitude of luminescent coupling (LC) between stacked subcells in multijunction photovoltaic devices. The effect of luminescence produced at high-band-gap subcells on underlying low-gap units within the same ...

Phenol-Formaldehyde Resin for Optical-Chemical Temperature Sensing

open access: yesSensors, 2018
The application of phenol-formaldehyde (PF) resin as an optical temperature sensor is investigated. Recent developments in optical luminescent sensors allow for global measurements to be made over the surface of a test article, extending beyond ...
