Differences of the Luminous Principle between Laser devices and LED devices
Bur Oak Secondary School, Markham, Ontario, L6E 1G4, Canada
The concept of luminescence has been a fascinating concept to mankind. The goal of this paper is to provide insights into the mysterious phenomenon of photoluminescence occurring from natural crystal lattice materials through electron radiation processes. The research methods used in the study involve the detection, identification, and interpretation of the structure, the working principle of the luminescence concept, and the application of the concept of luminescence from written materials. The methods extracted from the materials involve biological and biochemical lab methods based on the existence of phosphorescence, chemiluminescence, bioluminescence, and finally fluorescence. The study paper also highlights the differences between LEDs and LASERS, which are the main types of luminescence producing semiconductor devices. Their variations are presented in aspects of their working principle, the type of luminescence they produce, the respective output power, and the speed, transmitting distance & cost of each. Photoluminescence is a concept whose applications are widespread in the physical and chemical processes of our daily activities. Therefore, it is important to have a sufficient understanding of the successful applications of luminescent enhancement.
