Abstract
Thin films of five vanadium compounds/composite:(1) VO2(3-fl) (3-fl=3-Hydroxyflavone), (2) VO(pbd)2 (pbd=1-Phenyl-1, 3-butadione), (3) VO(dbm)2 (dbm=Dibenzoylmethane), (4) VPc (Vanadyl Phthalocyanine) and (5) V2O5-PEPC (V2O5-poly-N-epoxypropylcarbazole composite), were deposited by the drop-casting method from the solution in benzene. The transmittance-irradiance relationships were investigated and the transmission in the visible spectrum and optical images were obtained as well. It was found that the transmittance of the VO2(3-fl), VO(pbd)2, VO(dbm)2 and VPc, was practically independent of the irradiance; whereas the transmittance of V2O5-PEPC decreased by 4% for thin and 9% for thick film with an increase of the irradiance.-
