Scintillation and phosphorescence of PbWO4 crystals [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996
Abstract There are two types of crystals with respect to luminescence. In dc measurement, type A gives a primary emission at 410–430 nm (blue) with a second one at around 500 nm. Type B gives only dominant emission at 480–500 nm (green). This apparent difference can be interpreted as follows; the characteristic scintillation of PbWO4 is dominantly ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Measurements of anisotropic scintillation efficiency for carbon recoils in a stilbene crystal for dark matter detection [PDF]

, 2003
It is known that scintillation efficiency of organic single crystals depends on the direction of nuclear recoils relative to crystallographic axes. This property could be applied to the directional WIMP dark matter detector.The scintillation efficiency ...

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

Origin of scintillation in cerium-doped oxide crystals [PDF]

Applied Physics Letters, 1995
We propose here a model of the scintillation from complex oxide single crystals doped with Ce3+ ions to explain the correlation observed between scintillation light yield and intrinsic luminescence of the matrix.
