“…Red light emission from (600e630 nm) Eu 3þ doped phosphors are extensively used in lamp and display applications. Many Eu 3þ doped materials are being examined for use in new flat panel display technologies (Chen, Liu, & Li, 2004;Dubey, Tiwari, Pradhan, et al, 2014;Dubey, Tiwari, Tamrakar, et al, 2014;Meetei et al, 2012;Smits et al, 2010;Tamrakar, Dubey, Swamy, Tiwari, Pammi, Ramakrishna et al, 2013). Therefore, extensive amount of works have been reported on the properties of bulk and nanocrystalline ZrO 2 of different crystalline phases.…”
