Host absorption sensitizing and energy transfer to Eu3+ by Gd3+ in Ba6Gd2−xNa2Eux(PO4)6F2

Luminescent properties and energy transfer of Gd3+/Eu3+ co-doped cubic CaCO3

“…Gadolinium (Gd) was found to be a good sensitizer for europium (Eu) in different hosts due to their small energy gap between their certain energy levels which allow for energy transfer between them. For example, Mubiao Xie et al reported the host absorption sensitizing and energy transfer to Eu 3+ by Gd 3+ in Ba 6 Gd 2-x Na 2 Eu x (PO 4 ) 6 F 2 [20]. Jin He et al reported the VUV-vis photoluminescence of GdAl 3 (BO 3 ) 4 :Eu 3+ and energy transfer from Gd 3+ to Eu 3+ [21].…”

Photoluminescence characteristics of high thermal stable fluorosilicate apatite Ba2Y3(SiO4)3F:Sm3+ orange-red emitting phosphor

“…Apatite compounds have been confirmed to be efficient luminescence materials for cathodoluminescence and white LEDs (w-LEDs) [19][20][21][22][23][24][25]. The fluorine atoms have the largest electronegativity and exhibit strongest attractive electron ability and phosphors which contain the fluorine atoms are usually considered to be efficient luminescent materials because of excellent chemical and thermal stability [26,27]. Silicate-based phosphors also have superior stable crystal structure, high physical and chemical stability, and heat stability.…”

A Eu2+and Mn2+-coactivated fluoro-apatite-structure Ca6Y2Na2(PO4)6F2as a standard white-emitting phosphor via energy transfer

“…11 Recently, phosphors based on apatite-type fluorophosphates have attracted great attention since they show good chemical and thermal stability. 13 Hence, there is an increasing interest in the synthesis of novel, efficient, single-component white-emitting phosphors with structures derived from the apatite-type fluorophosphates family.…”
