- In practice, the quantum efficiency of photographic systems is often only about 20%. According to Slifkin (1972) the efficiency of silver halide photography is inherently “improbable”, and is due to a fortuitous combination of solid-state properties.

- The grain yield per absorbed quantum has been evaluated experimentally for four different photographic emulsions over a wavelength range of 1·-0.01 A., i e. from very soft X rays to gamma rays emitted from radium The tests were carried out with both heterogeneous and monochromatic X rays A grain yield of 1.0 per absorbed quantum appears to hold within a …
Equivalent quantum-efficiencies of photographic emulsions
- https://ui.adsabs.harvard.edu/abs/1958MNRAS.118..224F/abstract
- Signal-to-noise equivalent numbers of stored photons and equivalent quantum-efficiencies are derived for four emulsion batches from homogeneous sensitometry and data. The highest monochromatic efficiencies found are 0'9 per cent m the blue and per cent in the red. Peak efficiencies occur at densities of only to above fog. The peak equivalent number of photons …

- The relation of theoretical characteristic curves for monolayer ensembles of go-no-go detectors (emulsion grains) to quantum efficiency is developed. It is shown that the statistical fluctuations in the incident photons, as well as the fluctuations in the number of detectors made developable by a given exposure, preclude the possibility of achieving a quantum efficiency of unity.
Quantum Efficiency (QE) and Spectral Response

- • Quantum efficiency is defined as the percentage (or fraction) of incident photons that are detected [QE = # photons detected / # incident photons] • A detection can be defined in any number of ways, such as crystals formed (photographic emulsion) or charge-pairs created (CCD). The point is that the photon is recorded.
