Effect of doping of metal salts on polymers and their applications in various fields

Transition metal compounds (TMCs) provide the benefits of vast reserves, affordability, non-toxicity, and environmental friendliness, making them highly sought-after in recent times. Integrating transition metal salts into polymers may result in substantial enhancements in optical and electrical characteristics, making them appealing for many applications. Transition metal ions may display a range of electronic transitions, which enables the adjustment of absorption and emission spectra. This characteristic has significant value in applications such as light-emitting devices (LEDs) and sensors. The photoluminescence of polymers may be improved by the addition of transition metal salts, which results in light emission that is both more brilliant and more efficient. On the other hand, this is advantageous for screens and optoelectronic devices. The presence of transition metal salts in polymers may help to improve their optical stability, hence lowering the probability that the polymers will degrade or change color over time. When it comes to the performance of optical devices over the long run, this is quite essential. Elevating the electrical conductivity of polymers is possible via the use of transition metal salts. This is very helpful in the process of developing conductive polymers for use in applications such as electronic fabrics, organic solar cells, and flexible electronic devices. Transition metal salts can affect the electrical band structure of polymers, which enables the band gap of the material to be tuned. This is very necessary in order to maximize the amount of light that is absorbed by photovoltaic devices. Through having all these benefits, we conducted a review to find out the effects on polymeric materials.
