Question

Quizplus · Accepted Answer

Phosphorescence is the property of a material to emit light after being exposed to light. This is what causes certain objects or substances to glow in the dark, including some types of paint that contain radioactive materials. Phenolphthalein is a colorless chemical compound that is used as an acid-base indicator and does not glow in the dark. Radioactivity is the emission of ionizing radiation, but it is not a material or substance that glows in the dark. Neon is a non-toxic gas that is used in lighting and advertising signs, but it does not glow in the dark. Desensitivity is not a relevant term in this context.
