Results on the characterization of photoluminescent ...-based films, prepared from a sol-gel precursor and heat treated at 700...C, are reported for the first time. The samples showed two emission bands at 554 and 800 nm when excited with a 488 nm Ar-ion laser. The photoluminescent emission measured...
