Achieving blue emission via f→d transition from pyrochlore Eu2+ and Ce3+-doped La2Zr2O7 nanoparticles

Solid state lighting has been fetching the world attention in order to solve the global problem of energy crisis. In this context, phosphor-converted light-emitting diodes (pc-LEDs) are in high demand owing to their energy efficiency, longevity, and non-toxicity. In this work, we have taken an initiative of designing pyrochlore-based blue nanophosphors by doping La2Zr2O7 nanoparticles (NPs) with divalent Eu2+ and trivalent Ce3+ ions. The...
