The consequence of the site selective substitution of La3þ ions in modifying the local crystal structure in red emitting titanate perovskites and the resulting enhancement of the luminescence properties were investigated in two distinct series of red phosphors of Sr1-x-yLaxTiO3:yEu3þ and Sr1-x/2-yLa...
