Luminescent host lattices, LaInO3 and LaGaO3—A reinvestigation of luminescence of d10 metal ions

Abstract The phosphor LaInO 3 :Eu 3+ exhibits, in addition to the weak orange-red emission of Eu 3+ , a broad blue emission whose origin formed the basis for the reinvestigation of luminescence of LaInO 3 and the analogous LaGaO 3 , well known host lattices for luminescent centers. The results are analyzed based on the luminescence observed for In 3+ and Ga 3+ in various host lattices. An attempt is made to understand the mechanism of the luminescence of d 10 ions In 3+ and Ga 3+ .
