Rare‐Earth Mediated Engineering in ZnSe@ZnS:Eu3+ to Simultaneously Achieve Structural Modulation and Atomic Eu Doping Sites for X‐Ray Imaging

Advanced Science, Volume 13, Issue 47, 24 August 2026.
A dual hard‐base anchoring strategy was developed to synthesize ZnSe@ZnS:Eu3+ quantum dots, leveraging fluoride‐oleylamine interactions to create surface atomic Eu doping sites. By precisely tuning temperature, Eu3+ concentration, and fluoride levels, we obtain morphologies ranging from tip growth to coupled flower‐like structures.

Radioluminescence of synthetic and natural quartz

Radiation Measurements, 2012
Abstract The effect of X-ray irradiation and thermal treatments on the radio-luminescence emission spectrum of both a natural pegmatitic quartz and a synthetic one was investigated. All the emission spectra could be deconvolved into the same set of five Gaussian components.

Performance characteristics of a tungsten collimator and UVTRON flame sensor in the detection of alpha-induced radioluminescence

, 2020
It has been established that the UVTRON flame sensor (Hamamatsu) can detect alpha-induced radioluminescence, but that the presence of gamma and beta radiation both interfere with this detection.

Cerenkov and radioluminescence imaging of brain tumor specimens during neurosurgery [PDF]

, 2016
We presented the first example of Cerenkov luminescence imaging (CLI) and radioluminescence imaging (RLI) of human tumor specimens. A patient with a brain meningioma localized in the left parietal region was injected with 166 MBq of 90Y-DOTATOC the day ...

An automated system for the analysis of variable temperature radioluminescence

, 2001
Radioluminescence (RL, i.e. prompt luminescence emitted during exposure to ionizing radiation) is used for analysing luminescence emission processes and has been proposed as a method for determining received radiation doses in both natural and synthetic ...

Optically stimulated luminescence and spectral emission features of radioluminescence and thermoluminescence of natural kunzite:

, 2020
Features of luminescence optically stimulated from natural kunzite using 470 nm blue light are reported. Preparatory measurements of its X-ray excited radioluminescence and thermoluminescence show that the sample has two main bands centered at 360 nm and
