Sol-gel synthesis and thermal stability of luminescence of Lu3Al5O12:Ce3+ nano-garnet

▶ The LuAG:Ce3+ nano-garnet powder has been prepared by Pechini sol-gel method which are found to be agglomerated with an average particle size of 22 nm. ▶ The thermal stability of luminescence under 460 nm excitation of LuAG:Ce3+ up to 150 °C found to be better than YAG:Ce3+ nano-garnet. ▶ The LuAG:Ce3+ nano-garnet exhibits stable color co-ordinates with respect to temperature.
