“…This has been illustrated several times by enhanced fluorescence intensity and FLT in D2O. [62][63][64][65] The exact mechanism by which this quenching occurs and what parameters affect it is still to be fully understood and it is thus difficult to predict the extent of the effect.…”

The lipophilic natureo fo rganic dyes complicates their effectiveness in aqueous solutions. In this work we investigate threed ifferent strategies for achieving water-solubility of the diazaoxatriangulenium (DAOTA +)c hromophore: hydrophilic counter ions, aromatic sulfonationo ft he chromophore, and attachment of charged side chains. The long fluorescence lifetime(FLT, t f = 20 ns) of DAOTA + makes it a sensitive probet oa nalyze solvation and aggregation effects. Direct sulfonation of the chromophore was found to increase solubility drastically,b ut at the cost of greatly re-ducedq uantum yields (QYs) due to enhanced non-radiative deactivation processes. The introduction of either cationic (4) or zwitterionic side chains (5), however,b rings the FLT (t f = 18 ns) and QY (f f = 0.56) of the dye to the same level as the parent chromophorei na cetonitrile. Time-resolved fluorescence spectroscopya lso reveals ah igh resistance to aggregation and non-specific binding in ah igh loading of bovines erum albumin (BSA). The results clearly show that addition of charged flexibles ide chains is preferable to directs ulfonation of the chromophore core.

“…98,100 Recently, measurement of the lanthanide luminescence lifetime ratio between D 2 O and water also allowed for a more accurate and convenient calculation of the D 2 O concentration in water. 105,106 This same principle of lanthanide luminescence increase by D 2 O has been utilized in such diverse applications as the analysis of lanthanide ion-doped nanorods, 107 crystalline lanthanide sulfate hydrates, 108 and lanthanide-containing hydrogels. 109 In the case of lanthanide ion-doped nanorods, the authors explained the luminescence magnification by nanorods incorporating D 2 O as a decrease in multiphonon (excited lattice vibration modes) relaxation.…”

Created literally at the dawn of time, deuterium has been extremely valuable in so many chemistry roles. The subject of this review focuses on one deuterium application in particular: its enhancement of luminescence in many substances. After providing general overviews of both deuterium and luminescence, the early exploration of deuterium's effect on luminescence is described, followed by a number of specific topics. These sections include a discussion of deuterium‐influenced luminescence for dyes, proteins, singlet oxygen, and the lanthanide elements, as well as anomalous inverse deuterium luminescence effects. Future directions for this important research topic are also proposed, as well as a summary conclusion.

“…These analytical techniques suffer from several limitations including the necessity of transferring samples to a xed site, the use of expensive specialized analytical instruments, and complex analytical protocols requiring trained technicians. Recently, optical sensors have been developed for distinguishing between H 2 O and D 2 O via the physical interaction of the sensor with D 2 O and H 2 O [23][24][25][26][27][28] , or the detection of chemical variables such as acidity 29 . In the nuclear industry, the basic heavy water sensing technology includes beetle detectors, dew point sensors, gamma spectrometry, tritium beta activity monitors [13][14][15] .…”

We report the development and evaluation of a simple, inexpensive sensor capable of detecting liquid D2O and other isotopologues of liquid water through the measurement of electrical signals generated from a nano-porous alumina film. This electrical output, consisting of a sharp voltage pulse followed by a separate broad voltage pulse, is present during the application of microliter volumes of liquid. The amplitude and temporal characteristics of these pulses have been combined to enable four diagnostic parameters used for the sensing of D2O and H218O. The sensing mechanism is based on spatially localized variations in the surface potential of alumina, induced by isotopically substituted water molecules, combined with the effect of isotopic composition on charge transfer to the sensor. As a proof-of concept demonstration, a sensing system has been developed that provides real-time detection of liquid D2O in a stand-alone system.
