HIGH TEMPERATURE ZnSe:Mn/ZnS NANOPHOSPHORS WITH VERY HIGH QUANTUM EFFICIENCY FOR WHITE LEDs
… LED excitation. This thesis investigates doped nanophosphors that have unique high temperature emission well above room temperature. A novel technique for colloidal synthesis of ZnSe:Mn/ZnS nanocrystals (NCs) is also presented here, using a growth doping technique that exhibits a bright emission …

Nanophosphor-based Photonics
… the results are focused on specific types of nanophosphors that exhibit down-shifting, some of the results can be applied to other inorganic nanoparticles, such as those with up-conversion. The thesis also includes a study of the properties of oxyfluoride upconversion nanoparticle films and …

Collimator width Optimization in X-ray Luminescent Computed Tomography
… works by selective excitation of X-ray sensitive nanophosphors and detecting the optical signal thus generated. This system can be used towards recreating high quality tomographic slices even with low X-ray dose. There have been many studies which have reported successful validation of the …

A tri-modality x-ray fluorescence, x-ray luminescence, x-ray transmission computed tomography imaging platform for monitoring and stimulating metal-containing nanoparticles
… this platform’s ability to image X-PDT nanophosphors, such as Y2O3:Eu3+. This work also attempts to address the limitations of the system—sensitivity, acquisition time, and dosage—by examining how incoming X-ray irradiation schemes affect the X-ray fluorescent and X-ray luminescent …
