This research examines the structural and photoluminescence characteristics of two-dimensional molybdenum disulphide, focusing on how doping and defects affect light transmission in photonic crystal structures. Using computational techniques including the finite-difference time-domain and plane wave expansion methods, the investigation models periodic and aperiodic arrangements to determine photonic bandgaps. The analysis incorporates electromagnetic field distributions to evaluate how silver and gold doping, alongside varying defect sizes, alter the band structure and transmission behaviour. The findings demonstrate that doping with gold substantially modifies the photonic crystal structure, resulting in a considerable increase in the transmission spectrum. In contrast to silver doping, incorporating gold into the crystal structure yields optical performance that is more advantageous for light transmission systems.
Controlling how light moves through extremely thin materials is vital for creating faster and smaller optical technologies. By demonstrating that adding gold to two-dimensional molybdenum disulphide significantly boosts light transmission, this work provides clear guidance on how to engineer nanomaterials to guide light more efficiently in advanced electronic and optical systems.
The findings are relevant to designers and manufacturers developing optical transmission systems and waveguides for optoelectronic devices. Because the study relies on theoretical investigations and computational modelling of structural and photoluminescence properties, the research is at an early stage and requires physical fabrication and experimental validation before it can be applied in commercial hardware.

In this paper, we present the structural and photoluminescence (PL) spectra of 2D-MoS 2 and we report a theoretical investigation of the influence of Ag- and Au-doping on the transmission in 2D-MoS 2 photonic crystal structure (PCS). A finite-difference time-domain (FDTD) technique and plane wave expansion method (PWE) have been introduced and adapted for periodic and aperiodic structures to extract the PC-bandgap and study the behavior of the transmission spectrum. The impact of the size of defects, the Ag- and Au-doping on the 2D-PC band structure and transmission spectrum has been visualized under the inclusion of the distribution of electromagnetic fields and the associated field maps. It has been shown that the Au-doping changes significantly the 2D-MoS 2 PCS and as a result the transmission spectrum increases considerably. We can predict that 2D-MoS 2 PC doped with Au is more convenient than doped with Ag in most applications involving optical transmission and waveguides for optoelectronics devices.
