title: The Er3+-Yb3+ codoped La2O3 phosphor in finger print detection and optical heating.
abstract: The presence of impurities and morphological information about the Er(3+)-Yb(3+) 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.
