This paper reports a study on fluorescence sensing properties of cadmium telluride (CdTe) quantum dots (QDs) film under exposure of volatile organic compounds; ethanol, 2-propanol and acetone. The high luminescence QDs were synthesized using a wet-chemical process. CdTe QDs film was deposited onto the surface of fiber optic probe by drop-casting method. The fluorescence properties of the film were studied by observing the change of photoluminescence (PL) spectra of the films in nitrogen (N2) and after exposing in organic vapors. It was observed that the PL of the film was quenched by the presence of the organic vapors. The amount and the rate of quenching are depended on the kind of the organic vapors

Third order nonlinear optical properties were determined for phthalocyanine complexes 1–10 containing In , Ga and Zn central metals and tetra- or octa-substituted with benzyloxyphenoxy, phenoxy, tert-butylphenoxy and amino groups at peripheral or non-peripheral positions. The phthalocyanines were embedded in poly (methyl methacrylate) polymer in the presence of CdTe quantum dots. All complexes 1–10 were studied in the presence of CdTe quantum dots and embedded in poly (methyl methacrylate) to form thin films. Complex 3 tetrasubstituted with tert-butylphenoxy groups at non-peripheral positions was also studied in the presence of CdS , CdSe quantum dots, fullerenes, single walled carbon nanotubes. Third order nonlinear optical parameters generally increase for Pcs in the presence of CdTe quantum dots.

We demonstrated the inkjet-printed CdTe quantum dots-polyurethane acrylate thin films and their potential application in the display devices. The water soluble CdTe QDs were synthesized through the wet chemistry and the emission wavelengths can be freely tuned during the preparation process. Combining with the UV curable resin polyurethane acrylate, the QDs inks were prepared and the influence of diluent and water content on the performance of resultant films was studied. The tensile stress of the films cured from the QDs inks with diluent increased from 10.6 MPa to 27.5 MPa and the low water content led to uniform polymer matrix. Furthermore, the existence of diluent and low water content would all improve the fluorescence stability of the thin films. Finally, the thin films can be deposited on different substrates and well controlled to meet the RGB color standard, which will pave the way to a simple, low-cost, large-scale, and highly reliable method for the application of flexible displays.
