Photoluminescence behavior of Ti-doped Zn2SiO4 thin film phosphors

This work investigates the luminescent properties and structure of Zn2SiO4:Ti thin-film phosphor, before and after annealing up to 1000C. The Zn2SiO4:Ti films are fabricated by RF sputtering using ceramic target. After annealing at 800C the β-Zn2SiO4 phase is formed, but this phase is not suitable for the application in electroluminescence. The willemite structure (α-Zn2SiO4) is formed after an...

Cathodoluminescent Display Phosphors

The past several years rendered a resurgence of interest in phosphors for lowvoltage flat panel displays utilizing cathodoluminescence (CL). A major selection criterion for these phosphors is CL efficiency. The objective is to maximize the efilciency at low voltages. This work focuses on understanding the materials properties that influence CL efficiency below 1 kV. Existing high-voltage CL eff...

Storage Phosphors for Medical Imaging

Computed radiography (CR) uses storage phosphor imaging plates for digital imaging. Absorbed X-ray energy is stored in crystal defects. In read-out the energy is set free as blue photons upon optical stimulation. In the 35 years of CR history, several storage phosphor families were investigated and developed. An explanation is given as to why some materials made it to the commercial stage, whil...
