Abstract

•The latent finger print detection and laser induced heat generation has been explored.•The presence of impurities and morphological information has been carried out.•Fourier transform infrared spectroscopy and scanning electron microscopy (SEM) has been used.

The presence of impurities and morphological information about the Er3+–Yb3+ codoped La2O3 phosphors prepared by two different synthesis techniques have been obtained with the help of Fourier transform infrared (FTIR) spectroscopy and Scanning electron microscopy (SEM) respectively. The effect of synthesis process on the frequency upconversion (UC) emission with an excitation at 980 nm from laser diode radiation has been performed. The use of codoped phosphor in latent finger print detection and laser induced heat generation has also been explored.
