Dr. Bega Karadža: BiH scientist changing the future of LED technology

She was born in a small village in Bugojno, where she grew up and developed an interest in science.

Dr. Bega Karadža is a BiH scientist from Bugojno, specializing in researching LED technology and improving the efficiency of LED devices at the prestigious KU Leuven University in Belgium.

Throughout her doctoral dissertation, Dr. Karadža worked on innovative solutions in the field of LED technology using quantum dots, with a special focus on environmentally friendly InP quantum dots, which do not contain cadmium.

From Bugojno to KU Leuven

She was born in a small village in Bugojno, where she grew up and developed an interest in science.

After graduating from high school, she enrolled in physics at the Faculty of Science and Mathematics in Sarajevo. During her studies, she received a Baden-Wurttemberg scholarship, which enabled her to continue her master’s degree in photonics in Germany.

After completing her master’s degree, Dr. Karadža decided to broaden her academic horizons and applied for a PhD at KU Leuven, one of the most prestigious universities in Europe. With a full scholarship, she began research in the field of LED technology and optical modeling, focusing on quantum dots and the development of new LED solutions.

Innovations in LED technology

One of the key aspects of Dr. Karadža’s doctoral work is improving the efficiency of LED devices by reducing light losses and using environmentally friendly quantum dots. Through modeling quantum dots and developing new LED solutions, she has contributed to significant improvements in the energy efficiency and sustainability of LED technology.

“Quantum dots have the ability to absorb shorter wavelengths of light, like blue, and convert them into longer wavelengths, like green or red light. In layman’s terms, quantum dots can “change” the color of light,”  explained dr. Karadža.

Their specificity lies in the fact that only one type of material, such as indium phosphide (InP), can emit light in the entire visible spectrum by changing the size of the particle.

Dr. Karadža successfully defended her doctoral thesis in October 2024 and earned the title of Doctor of Engineering Technology.

Her research in the field of LED technology and cadmium-free quantum dots opens up new possibilities for environmentally friendly technologies that can significantly improve the efficiency of LED devices.

“LED technology has a problem with green and yellow light. By using quantum dots, we can more efficiently convert blue light into these colors,”  she explained.

The potential of quantum dots in industry

In addition to LED lighting, quantum dots have a wide range of applications in displays, sensors, and solar technology. In modern displays such as Samsung’s “NEO QLED” and “QD OLED”, quantum dots enable more accurate color reproduction and better energy efficiency. The nano-size of these particles also makes them ideal for integration with micro-LEDs, providing precise emission spectra.

“Although quantum dots have already been implemented in commercial devices, challenges such as stability still remain. When exposed to light, moisture or high temperatures, quantum dots can lose their effectiveness. “Current research focuses on finding solutions to these problems, especially for cadmium-free materials ,” she said.

Balancing private life and career

Balancing your private and professional life can be one of the biggest obstacles on the path to success, but it’s important to try to ensure that these two aspects of life are not in constant conflict.

Many people, in their efforts to be successful professionally, forget about important things in their personal lives, such as time spent with family and friends.

“However, success does not only mean career advancement, but also a successful private life. This does not mean that work should be neglected, but we should try to make room for family, friends and our own happiness”,  she pointed out.

The most important thing is not to let any aspect of our life stop us from our ideas, intentions and goals.

“Life is about balancing many roles and responsibilities, and success comes when we learn how to manage all of these aspects,”  she said.

Inspiration for young scientists and innovators

dr. Karadža showed by its example how it is possible to succeed in science and technology, even when you come from a small town.

Her message to young people is to get involved in various activities, join organizations that can help them in their professional and personal development.

“Develop skills that are not limited to academic pursuits, because life is much more than passing exams. Explore new paths, meet new people and build skills that will shape your future”,  she said.

This BiH scientist is a true example of how passion for science, perseverance and openness to new opportunities can lead to extraordinary success. Her story of her journey from a small village in Bugojno to a leading position in LED technology research in Belgium can be an inspiration to all young people who strive for scientific and professional excellence.
