A red emitting Li2BaP2O7:Tb3+ phosphor prepared through solid state reaction method is first time reported in this work. The main point of this work is that Tb3+ shows intense red line in addition to blue and green lines in Li2BaP2O7 upon UV excitation. Red line (602 nm) dominates the spectrum upon 372 nm excitation. However, the green line dominates the spectrum upon 230 nm excitation. The results are quite interesting from luminescence point of view. Therefore, we suggest anew red, green and blue emitting Li2BaP2O7:Tb3+ phosphor for pc-LEDs to generate white light. (C) 2016 Elsevier GmbH. All rights reserved.
