INTRODUCTION. Biophoton emission is a phenomenon that has been reported extensively in the literature (1–7).Photon emission from biological matter can occur both spontaneously and as a result of stressors such as visible light (), ultraviolet (UV) light (10, 11) and chemicals (4, 7).The spectrum of observed emission extends from the UV range (1, 6, 12) to the visible wavelength range (2, 4, 10).Cited by:
The relative numbers of optical photons emitted by a scintillator material per unit wavelength as a function of wavelength; the emission spectrum may also be given in alternative units such as wave number, photon energy, or frequency.
Photon emission following energy transfer from metastable species to suitable solid targets or to gas targets can be used for metastable detection, but because undirected fluorescence is normally detected with a rather low probability (compared to that for electrons or ions), this approach is less well suited for metastable detection if high sensitivity is needed.

Jul 11, · After an electron absorbs a photon, it will move to a higher energy state. It then releases a photon and returns to its ground state. But why does the electron release the photon? Why does it not remain in that energy state? What forces it to return to ground state? One way to look at it is that.
Purpose: The purpose of this study is to evaluate the added value of single photon emission computed tomography-computed tomography (SPECT-CT) over planar scintigraphy, SPECT and CT alone for characterization of isolated skull lesions in bone scintigraphy (BS) in cancer patients.
