Luminescence Property and Energy Transfer from Sm3+ ion to Eu3+ ion in LiEuxSm (1-x) W2O8 solid solution

Energy Transfer in Ion– and Laser–Solid Interactions

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Energy Transfer in Solid Argon during Ion Bombardment

Solid argon is a model system for studies of radiative and nonradiative processes associated with electronic excitation by MeV light ion bombardment. The electronic excited states, excitons and excimers, have been extensively studied in this material and careful studies have also been made of the ejection (sputtering) of atoms from the surface. The sputtering requires transfer of energy from el...

Luminescence properties and energy transfer in Tb3+ and Eu3+ co-doped Ba2P2O7 phosphors

The Ba2P2O7:Tb , Eu phosphors were synthesized by a high temperature solid-state reaction method in air atmosphere and their crystal structures, lifetime, luminescence properties, and energy transfer mechanism were investigated in detail. A series of characteristic emissions of Ba2P2O7:Tb , Eu phosphors were observed in the emission spectra at around 545 nm, 593 nm, and 613 nm when excited at 3...
