A series of La1−xGa0.99O3:Cr0.01, Ndx phosphors (where x = 0.005, 0.01, 0.02) for luminescence thermometry was synthesised by the solid-state method, structurally characterised using powder X-ray diffraction data, and investigated by ambient and variable-temperature optical measurements. The design principle relies on the use of a combination of transition metal and rare earth activator ions such that the excitation and emission wavelengths fall within the near infra-red spectral region, notably in the ‘first biological window’ that is attractive for potential in vivo applications. The photoluminescence spectra of the compounds feature the characteristic 2E phosphorescence of Cr3+ at 729 nm and the 4F3/2 → 4I9/2 emission of Nd3+ around 890 nm. The Nd3+ emission is quenched at a higher rate than that of Cr3+ with increasing temperature. Thermometric analysis by monitoring the luminescence intensity ratio (LIR) between the emissions of Cr3+ and Nd3+ from 300 K to 650 K shows a quasi-Bolt...zmann trend, with a maximum relative sensitivity of ∼2% K−1, high absolute sensitivity values over this entire temperature range, excellent temperature resolution of 0.04 K at room temperature, and high stability.
