(Universiti Malaysia Perlis (UniMAP), 2020-12)In this work, the first-principles calculations on the structural, electronic and optical properties of lanthanides (Ln)-doped anatase TiO2 using Ln elements from cerium (Ce), neodymium (Nd) and erbium (Er) were performed ... -
Improving the optical properties of porphyrin ring with different substitutions: As candidate using in photosensitizer
(Universiti Malaysia Perlis (UniMAP), 2020-07)In this research, different donor and acceptor substitutions were employed in attachment with porphyrin molecule and the optical properties improvement of it was studied. It was shown that the substituted porphyrin formation ... -
Observation of blue shift absorption for surface plasmon resonance in Gold Nano-Islands
(Universiti Malaysia Perlis (UniMAP), 2019-07)Controllable and predefined absorption are essential in the synthesis of new optoelectronic devices. In this work, an ion coater unit with a modified chamber is used to sputter the gold nano-islands onto glass substrates. ... -
Optical investigations of GaN deposited nano films using pulsed laser ablation in ethanol
(Universiti Malaysia Perlis (UniMAP), 2022-04)We provide an optical study on GaN thin film testing created by pulsed laser (ablation) in liquid. This study applied six different energies for ablated GaN nanoparticles in the liquid. According to the XRD test, the ... -
Optical, electrical and photovoltaic studies of γ-MnS thin films deposited by spray pyrolysis technique
(Universiti Malaysia Perlis (UniMAP), 2019-07)γ-MnS thin films were prepared on glass substrate by spray pyrolysis method at 280 °C. The optical constants and thickness of the films were extracted using the pattern search optimization technique in combination with a ... -
A preliminary study on structural and optical properties of heat treated NB2O5 nanostructure
(Universiti Malaysia Perlis (UniMAP), 2023-01)Annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to improve their crystalline structure and other important properties. This work presents the effect of post heat ... -
