Such structural dependence of electronic state will result in different excitation energy when these valence band states participate in optical transition
of point defects.
For example, firstly, effective isobaric suppression due to the unique isotopedependent optical transition
properties; secondly, high ionization efficiency; thirdly, high sensitivity with effectively low detection limit; and lastly, high isotopic selectivity (~[10.sup.13]).
TacticalRx glasses represent a very good investment in keeping you on-target through those years of optical transition
("degeneration" is such an ugly word!).
A disadvantage of [Ce.sup.3+] and [Eu.sup.2+] is that these ions in general show a large Stokes Shift, this being difference in energy between optical absorption and emission of the same optical transition
(which is also due to the fact that de d-states are extended in space and participate in the chemical bonding in the excited state).
The optical band gap is defined as the difference between the bottom of the conduction band and the top of the valence band, and it basically represents optical transition
. The absorption coefficient a needs to be determined first in order to determine the optical band gap of the films and is given by the following formula:
The power m takes several values depending on the nature of the optical transition
The reported band gap for bulk W[O.sub.3] is 2.6 eV, and for sol-gel derived nanocrystalline W[O.sub.3] films the variation of absorption edge for indirect optical transition
has been reported in the range of 2.6-3.2 eV .
The MCM can be placed on one end or both ends of the fiber link as an alternative to utilizing an optical transition
assembly, such as a breakout module or harness, at the link endpoints.
The variation in the frequency of the S-D optical transition
relative to NIST-F1 was found to be less than [+ or -] 10 fHz/Hz over the 2 years.
From the comparison of Figure 6 with plots obtained from Tauc's method (Figures 3-5), it can be observed that the optical transition
in PN1 and PN2 systems is forbidden direct transition type (i.e., n = 3/2), while PN3 system follows the forbidden indirect transition type (i.e., n = 3).
