Effect of Mn codopant on thermoluminescence properties of γ-rays irradiated Na3Y(PO4)2:Dy phosphors for dosimetry applications

Structural and luminescence studies of Eu3+ doped K2BaSr(PO4)2 phosphor

“…Through peak Chen's method [21], TL parameters such as frequency factors and activation energy are calculated for second order kinetics and shown in Table 1. The luminescence emission is due to the shallow and deep trap centers present in the K2BaSr(PO4)2 :Eu 3+ phosphor [22].…”

Elucidation of trap energies of Gamma-irradiated BaMgAl10O17: Ce3+ phosphors for dosimetry applications

“…Hence, Chen introduced a new approximation to solve trap energy without cumbersome iteration. Thus, the following equations with Chen's correction give the energy for firstand second-order kinetics, respectively [73].…”

Energy transfer properties of a single-phase Na3Gd(PO4)2:Eu2+,Mn2+ phosphor with excellent thermal stability for w-LEDs

“…The structural and spectroscopic properties of alkali metal lanthanide double phosphates, M 3 R(PO 4 ) 2 (R = trivalent lanthanide ions), doped with different lanthanide ions, have been the subject of considerable interest in the past due to their interesting optical properties, such as K 3 Eu(PO 4 ) 2 , 20 K 3 R(PO 4 ) 2 :R = Y and Gd, 21 Na 3 Y(PO 4 ) 2 , 22 Na 3 La(PO 4 ) 2 , 23 etc . The phosphors prepared with these hosts all showed excellent luminescence properties, so the phosphate Na 3 Gd(PO 4 ) 2 , as a member of the M 3 R(PO 4 ) 2 , system has attracted our attention.…”
