A series of anorthic phased Er³⁺/Yb³⁺/Li⁺/K⁺: ZnMoO₄ phosphors have been synthesized by solid state reaction method. Under 980 nm excitation, Er³⁺-Yb³⁺codoped phosphors exhibit intense green emission at ~531 nm/~553 nm corresponding to the ²H_11/2/⁴S_3/2 → ⁴I_15/2 and weak blue and red emissions at ~408 nm, ~474 nm and ~656 nm corresponding to the ²H_9/2 → ⁴I_15/2, ⁴F_7/2 → ⁴I_15/2 and ⁴F_9/2 → ⁴I_15/2 transitions, respectively. The multipolar interaction is found responsible for the concentration quenching. Furthermore, with incorporating the charge compensating agents Li⁺/K⁺ the UC emission intensity as well as temperature sensing performance have been perceptibly improved compared to the Er³⁺-Yb³⁺ phosphors. The fluorescence intensity ratio (FIR) technique have been performed to the thermally coupled (²H_11/2, ⁴S_3/2) levels and Stark sublevels (²H_11/2, ⁴S_3/2(I) & ²H_11/2, ⁴S_3/2(II)) to confirm the temperature sensing ability of the phosphors. The maximum sensitivity corresponding to the ²H_11/2, ⁴S_3/2(I) → ⁴I_15/2 & ²H_11/2, ⁴S_3/2(II) → ⁴I_15/2 transitions from the Stark sublevels have been observed.

通过固相反应法合成了一系列的原相定相的Er ³⁺ / Yb ³⁺ / Li ⁺ / K ⁺：ZnMoO ₄荧光粉。在980 nm激发下，Er ³⁺ -Yb ³⁺共掺杂的磷光体在〜531 nm /〜553 nm处显示出强绿色发射，对应于² H _11/2 / ⁴ S ₃ / ₂  →  ⁴ I _15/2和弱蓝和红色排放在〜408纳米，474〜nm和656〜纳米对应于² ħ _9/2  →  ⁴我_15/2，⁴ ˚F_7/2  →  ⁴我_15/2和⁴ ˚F _9/2  →  ^4个我_15/2跃迁，分别。发现多极相互作用导致浓度猝灭。此外，与 Er ³⁺ -Yb ³⁺ 荧光粉相比，通过加入电荷补偿剂Li ⁺ / K ⁺，UC发射强度以及温度感应性能得到了明显改善。荧光强度比（FIR）技术已用于热耦合（² H ₁₁ / ^2，4 S _3/2）和Stark子水平（² H ₁₁ / ^2，4 S _3/2（I）和² H ₁₁ / ^2，4 S _3/2（II））以确认荧光粉的温度感应能力。最大灵敏度对应于² H ₁₁ / ^2，4 S _3/2（I）  →  ⁴ I _15/2和² H ₁₁ / ^2，4 S _3/2（II） →  ⁴ I _15/2跃迁已经观察到鲜明的子级别。
