Host-to-activator energy transfer efficiencies in rare-earth doped YBO3 under vacuum ultraviolet excitation have been estimated using excitation and reflectance spectroscopy. From these data, relative electron–hole pair (e–h) trapping rate consta

Absorption of Vacuum Ultraviolet (VUV) radiation creates excited e – h pairs in rare – earth doped phosphors that can either be trapped by a defect state (killer) or Ln3+ activator. The e – h trapping efficiency by Ln3+ is proportional to the r

Understanding the factors that govern efficient host-sensitized luminescence remains an important element in the development of more efficient luminescent materials. In a doped phosphor system, absorption of high energy photons leads to the creation

Host — to — activator energy — transfer efficiencies under VUV excitation for YBO3:Tb3+ have been determined for three d — orbital trap states. Resulting calculations suggest the lowest in energy trap state is the primary trap for an electron

We have measured host-to-activator energy transfer efficiencies in rare-earth doped YBO3 under vacuum ultraviolet excitation. From these data, relative electron-hole (e-h) pair trapping rate constants can be estimated. Our analysis suggests a correla

We have conducted a systematic study of the excitation and reflectance spectra of nano-crystalline Y2O3:Eu prepared by combustion synthesis. Excitation through the host lattice becomes relatively more efficient as the firing temperature of the precur

Using reflectance and excitation spectroscopy, host-to-Eu3+ energy transfer efficiencies in YBO3:Gd,Eu under vacuum ultraviolet excitation have been calculated, at various concentrations of both dopants. As the Gd3+ concentration is increased, an inc
