application of polymers in novel and advanced scientific technologies is increasingly expanding. in this regard, optical polymers among different materials have found a special and unique position. a novel dye doped polymer thin film was prepared by taking advantage of dye molecules' interaction with the host environment. this sample, like self-assembled structures, makes use of this inter...

Precise control of particle positioning is desirable in many optical propulsion and sorting applications. Here, we develop an integrated platform for particle manipulation consisting of a combined optical nanofiber and optical tweezers system. We show that consistent and reversible transmission modulations arise when individual silica microspheres are introduced to the nanofiber surface using t...

Cadmium oxide thin films were fabricated on glass substrates by a simplified and low cost spray pyrolysis technique at different substrate temperatures. The X-ray diffraction study showed that irrespective of substrate temperature all the films exhibits a preferential orientation along the (1 1 1) plane. The values of crystallite size were found to be in the range 20.72 – 29.6 nm. The perce...

Yttrium Aluminum Garnet (Y3Al5O12) is a transparent ceramic with a wide range of applications such as high mechanical strength windows, high power laser sources and radiation detectors. The most important challenge in making these ceramics is the problem of low light transmittance, especially in the visible area in the range of 400 to 700 nm, which is greatly affected and reduced by various fac...
