Abstract

The formation of single-phase, morphological information and the impurities present in the developed phosphor has been identified by using x-ray diffraction, scanning electron microscope, and Fourier transform infrared analysis. Nontunable intense green upconversion emission from single-phase tetragonal Ho3+-Yb3+-codoped BaZnLa2O5 phosphor upon 980 nm excitation has been reported. The effect of codoping with Yb3+ ions on the upconversion emission bands in BaZnLa2O5:Ho3+ phosphor has been discussed, and the possible upconversion mechanisms involved have been explained. The experimental results confirm the suitability of the developed phosphor in display devices and security applications.
