[Fe(Htrz)(2)(trz)]BF4@SiO2 nanorods were synthesized using a reverse emulsion technique and a Tb3+ complex was chemically bound to the silica surface. This Tb-spin crossover nanocomposite demonstrates high luminescence stability under continuous thermal cycling. A reabsorption mechanism is determined to be responsible for the luminescence intensity variation during the spin state switching of the iron complex.
