A high-sensitivity dual-mode optical thermometry based on one-step synthesis of Mn2+:BaAl12O19–Mn4+:SrAl12O19 solid solution phosphors

A new type of phosphate-based phosphor Na3CsMg7(PO4)6:Eu2+/Mn2+with high quantum efficiency and high thermostability

“…4a and b. The excitation peak position by monitoring 630 nm emission is similar to other Mn 2+ -doped phosphors: 325 nm ( 6 A 1 → 4 E( 4 D)), 47 358 nm ( 6 A 1 → 4 T 2 ( 4 D)), 48 and 412 nm ( 6 A 1 → 4 A 1 ( 4 G), 4 E ( 4 G)), 465 ( 6 A 1 → 4 T 2 ( 4 G)). 49 The PL shows a sharp peak at about 630 nm with full-width at halfmaximum (FWHM) of about 65 nm.…”

Controllable crystal form transformation and luminescence properties of up-conversion luminescent material K3Sc0.5Lu0.5F6: Er3+, Yb3+ with cryolite structure

“…It shows that the synthesized samples belong to the cubic system, with a space group of Fd 3. [38][39][40] The samples for the two different crystal structures are all pure phases. The introduction of Er 3+ , Yb 3+ did not have any signicant inuence on the crystal form of KSLF.…”

Excellent upconversion luminescence and temperature sensing performance of CdMoO4:Er3+,Yb3+ phosphors

“…8 Among them, FIR techniques based on two thermally coupled energy levels have been extensively studied in the field of non-contact optical temperature measurement. [9][10][11] However, the application of this method is still not commercially available due to the limitation of temperature measurement sensitivity. Therefore, in order to meet increasingly demanding temperature measurement requirements, improving the sensitivity of non-contact optical temperature sensors is an urgent challenge to solve.…”
