Dyes having coumarin core which absorbs and emits in deep-red to NIR region have
become incredibly valuable due to their essential role in biology, DSSC, NLO materials, and …

The optical band gap energy and the electronic processes involved are important
parameters of a semiconductor material and it is therefore important to determine their …

In this work, a study of the photophysical properties in different solvents and at different pH
values of a luminogenic compound with a donor–π–acceptor (D–π–A) structure was carried …

A hybrid material based on a 1D copper chloride perovskite network with hexahydro-1, 4-
diazepine,(C5H14N2)[CuCl4], was grown at room temperature by slow evaporation. This …

The structural properties of ZnO/PMMA thin film are studied using FESEM, XRD and FTIR,
where uniform deposition of ZnO nanoparticles was observed in PMMA matrix. The FTIR …

Gas sensitivity improved and becomes more stable when a buffer layer (Al 2 O 3) inserted
between the active layer (Alq 3) and glass substrate. In this paper, we introduce a device …

A one dimensional copper (II)-based perovskite,(C5H8N3)[CuCl3], was successfully
synthesized. XR-diffraction demonstrates that the mineral framework of this perovskite is …

Ultraviolet photoelectron spectroscopy (UPS) is the most widely used technique to
determine the ionization energy (IE) of electronic materials, as this parameter is critically …

Bulk heterojunction (BHJ) organic solar cells have gained increasing attention in the past
few years. In this work, active layers of a wide-bandgap polymer donor with …

Modification of the ultrathin N, N′-Di (1-naphthyl)-N, N′-diphenyl-(1, 1′-biphenyl)-4, 4′-
diamine (NPB) insertion layer on the electronic structures of the CH3NH3PbI3 …
