Thermal and pump power effect in SrMoO4:Er3+-Yb3+ phosphor for thermometry and optical heating

Effects of Tm3+ concentration on upconversion luminescence and temperature‐sensing behavior in Tm3+/Yb3+:Y2O3 nanocrystals

“…Besides, the electron phonon interaction enhanced in the nanocrystals due to the quantum confinement of phonons, which also gave rise to the extra temperature rise . Hence, the strong laser‐induced heating enabled 0.1%Tm 3+ /5%Yb 3+ :Y 2 O 3 nanocrystals to be used as a simultaneous laser‐to‐heat conversion at higher pump powers, which could be applied in the application of hyperthermia‐based cancer therapy …”

Synthesis and up‐conversion of Er3+ and Yb3+ Co‐doped LiY(MoO4)2@SiO2 for optical thermometry applications

“…For optical thermometry, molybdates can be considered as good hosts for luminescence materials due to their excellent thermal and chemical stability. Different molybdates as host materials for optical thermometry have been studied intensively, such as NaGd(MoO 4 ) 2 , NaY(MoO 4 ) 2 , La 2 MoO 6 , SrMoO 4 , and etc . The large interspace of the molybdate structure can enhance the covalent character and improve the amount of rare earth ions absorbed into the matrix, thereby improving the luminous efficiency of the material.…”

“…The large interspace of the molybdate structure can enhance the covalent character and improve the amount of rare earth ions absorbed into the matrix, thereby improving the luminous efficiency of the material. Therefore molybdate phosphors co‐doped with Er 3+ and Yb 3+ have high a luminescent efficiency under excitation . In recent years, Er 3+ –Yb 3+ co‐doped molybdates have shown huge commercial prospect, where Er 3+ acts as an emitter and Yb 3+ acts as an absorber in the crystal lattice.…”
