“…Many defects absorb light at characteristic wavelengths in the ultraviolet (UV) to visible and infrared (IR) range, and can be detected using absorption spectroscopy. Once appropriately normalized, the integrated intensity of the absorption spectrum for a specific defect is proportional to its concentration, with defect-dependent detection limits that may be as low as a few parts per billion carbon atoms (Collins and Williams 1971;Davies 1981;Kiflawi et al 1994;Boyd et al 1994Boyd et al , 1995Lawson et al 1998;Howell et al 2019). Typically, fast Fourier transform infrared (FTIR) absorption spectra are collected at room temperature.…”

“…Blue or grayish blue HPHT diamonds containing sufficient uncompensated boron (i.e., an excess of boron compared to isolated nitrogen) to be classified as Type IIb show absorption features at ~2458, 2803, and 2930 cm −1 , with the latter feature having a tail which extends through the infrared into the red region of the visible spectrum (Collins and Williams 1971;Strong and Chrenko 1971;Koivula and Fryer 1984;Collins 1993b;Rooney et al 1993;Shigley et al 2004a,b;Howell et al 2019;Green et al 2022, this volume). Boron readily incorporates into the growing diamond lattice, and may be added intentionally to the growth capsule.…”

“…It is already known that [64,70], where the suffix of {hkl} refers to the {hkl} growth sector. Accordingly, the boron incorporation is normally much less (∼1/100) in the {100} sectors than in the {111} sectors [70,71], reducing the number of BV in the {100} sectors of our crystal.…”

Impurity-vacancy complexes in diamond are an attractive family of spin defects since NV -, SiV -, GeV -, and SnVhave emerged as promising platforms for quantum applications. Although boron is most easily incorporated into diamond, a boron-vacancy complex in the negative charge state (BV -) has eluded experimental observation. This center was theoretically predicted as another promising spin qubit. In this work, we experimentally observed an electron paramagnetic resonance (EPR) spectrum identified as BVin synthetic diamonds via a Fermi-level tuning. Fingerprints of BVsuch as the spin multiplicity of S = 1, C 3v symmetry, and the zero-field splitting (D = 2913 MHz), in addition to 10 B and 11 B hyperfine (HF) interactions, have been confirmed. Moreover, optically pumped spin polarization has been observed with 3.0-3.6 eV excitation. However, unlike the NVcenter, the photoluminescence as well as optically detected magnetic resonance from BVhave not been confirmed even at low temperatures. We speculate that the Jahn-Teller instability in the triplet excited states of the NVand BVcenters results in different optical properties.

“…While this article has focused on several gemological applications and scientific research using Raman and PL mapping, other applications on gem materials not recounted here have also been studied [78][79][80][81][82][83][84]. Additionally, similar research aims have involved other mapping technologies such as IR absorption mapping [85][86][87][88][89], cathodoluminescence mapping [90][91][92][93][94][95], chemical analysis using LIBS [96] or X-ray fluorescence [97], electron paramagnetic resonance (EPR) imaging [98], and fluorescence decay (luminescence lifetime) mapping [99,100]. In the future, we expect that instrumentation will be able to integrate these various technologies together.…”

Raman and Photoluminescence Mapping of Gem Materials

Raman and photoluminescence (PL) mapping is a non-destructive method which allows gemologists and scientists to evaluate the spatial distributions of defects within a gem; it can also provide a method to quickly distinguish different species within a composite gem. This article provides a summary of this relatively new technology and its instrumentation. Additionally, we provide a compilation of new data for various applications on several gemstones. Spatial differences within diamonds can be explored using PL mapping, such as radiation stains observed on the rough surface of natural green diamonds. Raman mapping has proven useful in distinguishing between omphacite and jadeite within a composite of these two minerals, identifying various tourmaline species within a heterogeneous mixture, and determining the calcium carbonate polymorphs in pearls. Additionally, it has potential to be useful for country-of-origin determination in blue sapphires and micro-inclusion analysis. As new avenues of research are explored, more applications for gem materials will inevitably be discovered.
