Thermoluminescence and photoluminescence study of caso4: Dy nanophosphor for 6 mev energy electron dosimetry

The influence of different synthesis routes on thermoluminescence of CaSO4: Dy, P, Ce phosphor

CaSO4: Dy, P is known for its dosimetric characteristics for a very long time now. In this work we have carried out a comparative study on TL intensity of CaSO4: Dy, P, Ce phosphors using two different wet chemical synthesis routes. Nobody seems to have reported this kind of study on CaSO4: Dy, P, Ce 3+ phosphors and as a result it may be regarded as something new. Phosphors were characterized ...

Synthesis and Photoluminescence Properties of HEu1-xGdx(MoO4)2 Nanophosphor

New HEu1−xGdx(MoO4)2 nanophosphors were synthesized by a simple one-step ion-exchange method. These nanophosphors have rod-like particle morphology with 0.5–15 μm in length and outer diameters in the range of 50–500 nm. By optimization of the composition, the highest emission intensity was obtained for the samples with x = 0.50 for both KEu1−xGdx(MoO4)2 and HEu1−xGdx(MoO4)2. key words: Nanophos...

Dosimetric comparison of 4 MeV and 6 MeV electron beams for total skin irradiation

BACKGROUND In this study, dosimetric aspects of TSEI consisting of a 4 MeV beam with no spoiler were investigated in comparison to a nominal 6 MeV beam with spoiler, and the potential for clinical applications was evaluated. METHODS The TSEI technique is based on the Stanford technique, which utilizes a beam configuration of six-dual fields. MOSFETs were used to measure the optimal gantry ang...

Simulation of MeV electron energy deposition in CdS quantum dots absorbed in silicate glass for radiation dosimetry

We are currently developing 2D dosimeters with optical readout based on CdS or CdS/CdSe core-shell quantum-dots using commercially available materials. In order to understand the limitations on the measurement of a 2D radiation profile the 3D deposited energy profile of MeV energy electrons in CdS quantum-dot-doped silica glass have been studied by Monte Carlo simulation using the CASINO and PE...
