Neodymium (Nd3+) doped fluoride nanocrystals are the commonly investigated due to the fact that the Nd3+ excitation and emission lie within the biological window regions (700–1500 nm) where the transparency of living tissue is high (due to low optical absorption)1,2, offering much potential for deep-tissue imaging3 and temperature sensing4. So far, the many reports on Nd3+ doped materials focus upon concentration dependent near-infrared emission1-4 however, there are not many studies that report the concentration dependence on their absorption spectra. It is important to gain knowledge of the wavelength of the absorption maxima to enhance the emission intensity of the nanoparticles for applications in bio-medicine. In this study we have hydrothermally synthesized neodymium Nd3+ ion doped KY3F10 nanoparticles varying different Nd3+ ion concentrations. The effect of Nd3+ ion concentration on their absorption maximum in three biological window regions have been recorded using a high resolution FTIR absorption spectroscopy.
