Claims
- 1. A fluorescent polymer containing x nonfluorescent monomer units having the structural formula ##STR18## and y fluorescent monomer units having the structure ##STR19## wherein x and y are integers in the range of approximately 1 to 200,
- and further wherein the polymer is bound to the surface of a substrate.
- 2. The polymer of claim 1, wherein the sum of x and y is less than about 200.
- 3. The polymer of claim 2, wherein the substrate is an optical fiber.
- 4. The polymer of claim 3, wherein the optical fiber is comprised of an organic material.
- 5. The polymer of claim 4, wherein the organic material is selected from the group consisting of polymethylmethacrylate, polystyrene, polymethylphenyl siloxane and deuterated methyl methacrylate.
- 6. The polymer of claim 3, wherein the optical fiber is comprised of an inorganic material.
- 7. The polymer of claim 6, wherein the inorganic material is glass.
- 8. A surface-bound fluorescent polymer having the structure ##STR20## wherein: x and y are integers in the range of approximately 1 to 200; and
- * represents the point of attachment of the polymer to the surface of a substrate.
- 9. The surface-bound fluorescent polymer of claim 8, wherein the substrate is an optical fiber.
- 10. The surface-bound fluorescent polymer of claim 9, wherein the optical fiber is comprised of an inorganic material.
- 11. The polymer of claim 10, wherein the inorganic material is glass.
