Magnesium aluminate (MgAl2O4) doped with terbium was prepared by combustion synthesis. Defect centres of MgAl2O4:Tb are studied by correlating various techniques such as Electron Spin Resonance (ESR), Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL). TL studies on MgAl2O4:Tb 3+ show two TL peaks at 120 and 340°C. MgAl2O4:Tb 3+ exhibits(More)
Properties such as high optically stimulated luminescent (OSL) sensitivity, ease of preparation and dose linearity over nine decades (µGy-kGy) make LiMgPO4:Tb, B (LMP) a unique phosphor for dosimetry applications. This led to the investigation of the beta response of highly sensitive LMP-based Teflon-embedded OSL discs for personnel monitoring applications.(More)
This work concentrates on the mathematical modeling of High Electron Mobility Transistors (HEMTs). Fermi-Dirac distribution characteristics of HEMTs and Silicon Nano-wire Transistors (SNWTs) were compared. Our mathematical modelling involves study of V-I characteristics, Electric field versus Drift velocity characteristics, ID electron density versus(More)
