A sensing arrangement for measuring physical parameters or concentration of particles is assembled of a laminar source of luminescent radiation. Fluorescent indicating particles are arranged in an indicator layer adjoining one major side of the laminar light source. The indicator layer adjoins a measuring space containing the object of measurement whose particles enter the indicator layer by diffusion. Fluorescent indicating particles are arranged in the indicator layer to emit fluorescent light when illuminated by the laminar light source. Photoelectric receiver is adjacent the opposite side of the laminar light source to measure the intensity of the fluorescent radiation. In a modification, luminescent phosphors and fluorescent particles are arranged in a common matrix.
