Modulating Mn self-reduction and multimodal luminescence in CaSb2O6 through La3+ doping for quadruple-mode dynamic anti-counterfeiting and optical temperature sensing applications

The co-doping La 3+ strategy was employed to modulate Mn self-reduction and multimodal luminescence in CaS 2 O 6 :Mn. CaS 2 O 6 :Mn has potential application in optical anti-counterfeiting and high-sensitivity temperature sensing applications.
