Dyeing crystals
Abstract
The art and science of dyeing crystals began in 1854, when Henri de Sénarmont attempted to demonstrate artificial pleochroism. Herein, an explicit historical account of the evolution and expansion of the science of dyeing crystals into an independent field of research is graphically illustrated. Past research is organized topically and chronologically, while the contemporary subjects are organized in terms of application. A comprehensive index of dyed crystals, organized by crystalline material, has been prepared from an extensive search of all dyed crystals in the literature from 1854 to 2000. The specific contributions of the use of luminescent probes or luminescent dyes to study crystal growth are expounded upon. Luminescent probes that form dye inclusion crystals (DICs) have been employed to visualize the active growth surfaces of the crystals at the onset of incorporation. The identification of surface structures and the selective partitioning of luminescent probes within specific regions defined by the surface topography aid in the identification of incorporation mechanisms. The properties of the luminescent probes are also effected by the crystalline environment, and the use of crystals to study luminescent probes is illustrated. The encapsulation of luminescent probes within crystals has been determined to be the operative mechanism for Solid-Surface Room Temperature Phosphorescence from inorganic crystalline supports.
