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 dropcasting 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 films with an increase of the irradiance.
Thin films of five vanadium compounds / composite: (1) VO2 (3-fl) (3-fl = 3-Hydroxyflavone), (2) VO (4) VPc (Vanadyl Phthalocyanine) and (5) V2O5-PEPC (V2O5-poly-N-epoxypropylcarbazole composite), were deposited by the dropcasting 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 VO 2 (3-fl), VO (pbd) 2, VO (dbm) 2 and VPc, was practically independent of the irradiance; while the transmittance of V2O5-PEPC decreased by 4% for thin and 9% for thick films with an increase of the irradiance.
