Luminaalinen is a Finnish adjective that translates to luminescent or luminous. It describes something that emits light, either through a chemical process or by reflecting ambient light. This term is often used in scientific contexts, particularly in chemistry and physics, to refer to substances that exhibit luminescence. Luminescence is a broad term encompassing phenomena like fluorescence and phosphorescence, where light is produced without significant heat.
