Despite the mentioned prospects, practical implementation of lasers based on color centers in diamond is limited to laboratory demonstrations. No commercially significant products of laser technology based on diamond with color centers have been created yet. Obviously, the available scientific information is still insufficient, and additional research is required. The review analyzes the factors that require further study: concentration quenching of luminescence, thermal quenching of luminescence, luminescence quenching by nitrogen and other impurity defects, as well as the influence of multiphoton and multi-stage absorption processes. For color centers in diamond, such processes have yet to be investigated in more detail.","PeriodicalId":296561,"journal":{"name":"Luminescence and Laser Physics: XVII International Conference on Luminescence and Laser Physics – LLPh 2019","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128886034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accumulation of currents in the studied material in absence of external voltage is connected with electrical activity of the system and the generation of a stable internal electric field in this system. The electric field generated in a heterogeneous medium formed by fine-dispersed lithium fluoride and a water film, causes ionization of polar water molecules that produce conductivity channels. This leads to active electrical interaction of the surfaces of solid and liquid dielectrics included in structure of the system under study. The presence of radiation induced defects in the dispersed phase based on LiF influences the processes of interphase interactions. This contributes to formation of deep electron traps and increases the lifetime of the charge of electrets.","PeriodicalId":296561,"journal":{"name":"Luminescence and Laser Physics: XVII International Conference on Luminescence and Laser Physics – LLPh 2019","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126847226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After single-pulse irradiation, a band with maximum at wavelength of 450 nm related to formation of F3 color centers was observed in the extinction spectra of sample. With an increase in the number of pulses, components associated with more complex aggregate F3 (R), F3, and F4 (N) centers appear in the band structure. The observed association of F3+ centers leads to the formation of larger aggregates up to the precipitation of nanoscale lithium clusters, which is confirmed by comparison of spectra of the crystals irradiated with laser pulses and the crystals irradiated with high-energy Li+ ions with use of ion implanter. Atomic force microscopy study confirmed the conclusion that lithium nanoparticles with sizes in the range of 60–90 nm were formed in surface layer of LiF crystal as a result of laser irradiation.","PeriodicalId":296561,"journal":{"name":"Luminescence and Laser Physics: XVII International Conference on Luminescence and Laser Physics – LLPh 2019","volume":"484 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131881459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
