Quantum gain in photosensitive materials: the domino mechanism

Not Accessible

Your library or personal account may give you access

Abstract

It is shown that if a matrix contains a photochemically active molecule whose photoproduct is capable of undergoing energy transfer back to the starting material, high quantum gains may be obtained without further chemical processing. After establishing the equation for quantum gain in solid matrices, the necessary molecular properties and experimental conditions for observing a quantum gain are determined. Obtaining quantum gain with this dry process may be useful in increasing the sensitivity in optical data storage and in photoresist and photographic processes.
