Painted radioluminescence imaging with radioluminescent nanophosphors
Applied Physics Letters, 2022Optical strategies like Cerenkov luminescence imaging (CLI) or radioluminescence imaging (RLI) to image clinically available positron emission tomography and single photon emission computed tomography probes still suffer from low sensitivity or resolution.

Towards the Development of Doped Silica Radioluminescence Dosimetry
Radiation Physics and Chemistry, 2019 We discuss recent investigations by members of this group concerning the performance of P-doped silica for radioluminescence-based dosimetry. Comparisons are made against that of an in-house developed Ge-doped silica system and carbon-doped alumina ...

Radioluminescence investigation of Nasicon materials
Materials Research Bulletin, 2000The X-ray excited luminescent emissions of samples of Nasicon (NASuper-Ionic-CONductor) compounds of different stoichiometries were recorded vs. wavelength in the 280 to 560 nm range. The spectra show main peaks near 300 nm, with wavelengths and intensities depending on the sodium content of samples. These peaks are ascribed to radiative recombinations

Thermoluminescence and radioluminescence in aragonite
Mineralogy and Petrology, 1988Thermoluminescence (TL) and radioluminescence (RL) wavelength spectra of aragonite have been investigated. Despite the different origin of the samples used, a number of common luminescence features emerges. The spectra for TL peaks appearing near 50, 70 and 170 K are identical with a prominent and broad band centered near 400 nm.

On the radioluminescent emission of BaF2
Il Nuovo Cimento D, 1996The luminescence of barium fluoride excited by X-rays has been recordedvs. wavelength. The spectrum shows two components due to recombination of excitons bound to Frenkel defects and to luminescent centres also active in the thermoluminescent process. The results are interpreted by means of a model based on the Prener and Williams recombination scheme.

Radioluminescence of alkaline ices
Radiation Physics and Chemistry (1977), 1981Abstract The reactions of electrons in alkaline glasses containing 5–20 M NaOH were studied by isothermal luminescence (ITL) after γ-irradiation at 77 K and by radiothermoluminescence (RTL). Both ITL and total RTL emission are influenced by NaOH concentration in a similar way revealing a minimum at 8–10 M NaOH.

Characteristics of radioluminescence in crystals
British Journal of Applied Physics, 1954Measurements of scintillation light output versus α-particle energy are made for single crystals of organic and inorganic substances excited by monoenergetic α-particles. A new method is used to deduce a relation between the differential efficiency dL/dx and the specific energy loss dE/dx, which in the case of calcium fluoride is verified ...

Radioluminescence of some optical fibres
Physics in Medicine and Biology, 2007Measurement of radiation fields with small scintillators as detectors for radiation dose is an attractive method provided that the scintillator luminescence can be discriminated against other unwanted signals. In diagnostic radiology radioluminescence of the optical fibres required for a transmission of the luminescence to an optical detector is the ...

Radioluminescence of Biopolymers and Their Components
1969A wide variety of inorganic and organic substances luminesce under the effect of X rays or radiation from radioactive sources; these substances include proteins, nucleic acids, and their components. Reports on the radioluminescence of DNA will be found in monographs by Tarusov (1955) and Dubinin (1961).
