Fotoluminescência: uma abordagem experimental para o ensino de física quântica

Abstract

The advent of Quantum Physics has revolutionized our understanding of reality by challenging previously intuitive concepts established by Classical Physics. Currently, it holds profound implications for modern technology, and its comprehension is crucial for fostering critical and participatory citizens within their respective social realities. Therefore, there is a growing need in basic education, which aims to educate individuals holistically for life in society, to teach even introductory topics of Modern and Contemporary Physics. Addressing this need in Physics Education, this study aims to develop and implement a didactic sequence for teaching Quantum Physics in high school through experimental approaches integrated with the methodology of three pedagogical moments. The study primarily investigates photoluminescence phenomena (fluorescence and phosphorescence) to problematize and cover topics such as blackbody radiation and energy quantization, the photoelectric effect and photon theory, Bohr's atomic model, and interactions between electromagnetic radiation and the human body. Results from the educational intervention reveal indications of satisfactory learning outcomes, as evidenced by the analysis of pre- and post-application questionnaires. This points towards a significant progression in student’s knowledge of introductory quantum physics concepts in high school.
