Using solid-state reaction technique, we prepared a series of Bi 3+/Eu 3+-activated GdNbO
4 phosphors. Under 308 nm excitation, the energy transfer from Bi 3+ to Eu 3+ ions, which …

In this report, a series of novel KBaY (MoO4) 3: Yb3+, Ho3+ (KBYMO: Yb3+, Ho3+) materials
with intense up-conversion (UC) luminescence properties were synthesized using a high …

To date, non-contact luminescence thermometry methods based on fluorescence intensity
ratio (FIR) technology have been studied extensively. However, designing phosphors with …

Non-contact remote optical thermometers as a significant technique have been extensively
developed. However, it is still a challenge to design new Bismuth-doped phosphor materials …

For a long time, rare-earth ion-doped phosphors have been widely used in temperature
sensing because of their excellent light-emitting properties. However, most of the rare earth …

Abstract In this work, Ca 3 MgSi 2 O 8: R (R= Dy 3+, Eu 3+, and Eu 3+/Dy 3+) phosphors are
synthesized in air by using the high-emperature solid-state reaction method. The crystal …

We report a change in the red photoluminescence of the Eu 3+ doped Na 2 Sr 2 Al 2 PO 4 Cl
9 phosphor via doping of singly, doubly and triply ionized ions. The synthesized phosphors …

Abstract Bi 3+, Eu 3+ singly doped and Bi 3+/Eu 3+ co-doped Ca 9 MgLi (PO) 7 (CMLPO)
with a single pure phase are synthesized in air by high-temperature solid-state method and …

Here, we report features of YVO 4: Sm 3+ nanocrystalline powders prepared via modified
Pechini technique. Doping concentration effect on structural and luminescence properties …

To overcome the existing challenge of temperature monitoring with high accuracy, we
designed Sm3+-doped LiSrVO4 phosphors with ultra-high sensitivity as promising …
