Spectral and thermometric properties altering through crystal field strength modification and host material composition in luminescence thermometers based on Fe 3+ doped AB 2 O 4 type nanocrystals (A = Mg, Ca; B = Al, Ga)

The influence of the crystal field strength and host material composition on the spectral position of the emission band and thermal stability of Fe ³⁺ luminescence was investigated in order to develop a highly sensitive luminescence thermometer.
