AB  - The first biological window (650–950 nm) is the area within the NIR spectrum able to penetrate skin more effectively than shorter wavelengths.1 The TM3+, Ln3+ activator combination has attracted attention due excitation/emission within this wavelength range.2 In this investigation, a series of La1-xGa0.99O3: Cr0.01, Ndx phosphors (where x = 0.005, 0.01, 0.02) were synthesised by conventional solid-state methods and structurally characterised by Rietveld refinement of a structural model and powder diffraction data.3 Room temperature photoluminescence was undertaken with excitation spectra of both the Cr3+ and the Nd3+ showing energy transfer to the other emission centre alongside showing the characteristic Cr3+ broadbands, and sharp Nd3+ line excitations. Emission spectra showed both the Cr3+ 2E sharp peak at 729 nm, and the Nd3+ 4I3/2  4I9/2 emission of Nd3+ ca. 890 nm.  Variable temperature thermometric analysis was undertaken, with the La1-xGa0.99O3: Cr0.01, Ndx (x = 0.02) sample exhibiting the emissions from the Cr3+ and Nd3+ centres at comparable intensities. Monitoring by luminescence intensity ratio (LIR) showed Cr3+ emission being quenched slower than Nd3+ emission. The phosphor produced a relative sensitivity of ~2.0% K-1 at 300 K, high absolute sensitivity, and a temperature resolution of 0.04 K at 300 K.
