increasing and biofilm damage in intimate coupling of photocatalysis and biodegradation …

Abstract Ho 3+/Gd 3+ co-doped YbNbO 4 phosphors were successfully synthesized by the
high-temperature solid-state method. The crystal structure, morphology structure, element …

Abstract Cr 3+→ Ln 3+ energy transfer (Ln= Nd or Yb) is investigated for the first time in Al 2
O 3 host. Intense near infrared (NIR) emission around 1 μm is obtained as a result of this …

Er 3+ single-doped and Er 3+, Yb 3+ co-doped NaY (WO 4) 2 phosphors were synthesized
at 1100° C by a solid-state reaction method. The samples were characterized by XRD and …

To date, the mechanisms of Er3+ upconversion luminescence via 980 and 1530 nm
excitation have been extensively investigated; however, based on discussions, they either …

Glasses having composition 20ZnO⋅ xSiO 2⋅(79.5− x) Bi 2 O 3⋅ 0.5 Nd 2 O 3 with x
varying from 10 to 50 mol% have been synthesized. The amorphous nature of the glasses …

Upconversion (UC) luminescence and ferroelectric (FE) polarization properties were first
investigated in polycrystalline Er 3+-doped SrBi 2 Nb 2 O 9 (SBN: xEr 3+) samples. Bright …
