Increased Utility Of Ph Sensitive Indicators As High Concentration Co2 Detectors Through The Use Of Polyelectrolyte Complexes As Stabilizing Media, Camden James Johnson
Increased Utility Of Ph Sensitive Indicators As High Concentration Co2 Detectors Through The Use Of Polyelectrolyte Complexes As Stabilizing Media, Camden James Johnson
All Master's Theses
Development of plastic materials which produce visible color change when exposed to different environments has recently attracted attention for many biomedical applications.1,2Many biomedical devices are packaged under high concentrations of carbon dioxide (CO2) which can lower the pH of the packaging environment. This is similar to the CO2 chemistry responsible for ocean acidification.3 Dye molecules that are sensitive to environmental changes in pH (known as pH indicators) can be encapsulated in plastics and produce a visible color change when a medical device is removed from the sterile CO2 environment. Plastics made from large …
Investigation Of Host-Sensitized Luminescence Of Trivalent Lanthanide Doped Yttrium Phosphate Using Vuv Spectroscopy, Zachary Way
Investigation Of Host-Sensitized Luminescence Of Trivalent Lanthanide Doped Yttrium Phosphate Using Vuv Spectroscopy, Zachary Way
All Master's Theses
Host-sensitized luminescence of yttrium phosphate doped with trivalent lanthanide elements prepared via two synthetic approaches was studied using VUV spectroscopy. A correlation between an unusually intense 150 nm excitation intensity and the ground state energy level of select trivalent lanthanide elements was proposed. Using spectroscopy, the host-to-activator transfer efficiencies of YPO4:Ln3+ (Ln3+ = Sm3+, Eu3+ and Tb3+) were evaluated for two synthetic approaches. Electron-hole pair trapping efficiencies and Sloss values were calculated using published kinetic models.
