“…This method was previously used in development of scintillation ceramics Gd2O2S:Pr,Ce [55] and ZnO:Zn [56]. ZnO-ceramics were obtained using powderlike zinc oxide with an initial particle size in the range 90-600 nm [57][58][59][60]. Figure 6 presents X-ray luminescence spectra ZnO and ZnO:Ga ceramics in comparison with the spectrum of the well_known BaF2 scintillator.…”

Abstract-We generalize and systematize basic experimental data on optical and luminescence properties of ZnO single crystals, thin films, powders, ceramics, and nanocrystals. We consider and study mechanisms by which two main emission bands occur, a short-wavelength band near the fundamental absorption edge and a broad long-wavelength band, the maximum of which usually lies in the green spectral range. We determine a relationship between the two luminescence bands and study in detail the possibility of controlling the characteristics of ZnO by varying the maximum position of the short-wavelength band. We show that the optical and luminescence characteristics of ZnO largely depend on the choice of the corresponding impurity and the parameters of the synthesis and subsequent treatment of the sample. Prospects for using zinc oxide as a scintillator material are discussed. Additionally, we consider experimental results that are of principal interest for practice.

“…Scintillation light yield of ZnO was set to 9000 photon/MeV [23]. Also, X-ray induced luminescence spectrum and optical absorption/scattering coefficients of ZnO were similar to what previously reported in [24,25].…”

Fabrication, testing and simulation of a high spatial resolution alpha-particle imager based on ZnO nanowires in a polycarbonate nanoporous membrane

A new architecture consisting of ZnO nanowires embedded in a polycarbonate nanoporous membrane was proposed, fabricated and simulated as a high spatial resolution alpha particle imager. The experimental and Geant4 simulation results showed that ZnO nanowires could act as scintillating fibers to prevent spread of the generated optical photons inside the imager. This property can be used to precisely determine alpha collision coordinates. An array of these nanowires can be also applied as a new high spatial resolution alpha particle imager.

“…Furthermore, recent studies of ZnO nanorods have yielded strong evidence that the visible emissions located at 2.5 and 2.2 eV can be attributed to singly-charged oxygen vacancies (VO+) and doubly-charged oxygen vacancies (VO++) respectively 40 . There has been a steady increase in research focusing on ZnO as a scintillating material over the last decade [41][42][43][44][45][46][47][48][49][50][51] . Some of the properties of ZnO that are appealing for scintillation applications include: high quantum efficiency light output 52 , sub-nanosecond response times 53 , and higher radiation hardness than other semiconductor materials such as Si, GaAs, or GaN 54 .…”

To my mom, Linda.iii ACKNOWLEDGEMENTSThere are no words to express how grateful I am for all the people that have been part of my life during this journey. I could not have completed my PhD without their help, and I would first like to thank the two advisors that guided me through my graduate career.Professor Richard Mu accepted me as an REU student during my final summer as an undergraduate. After interacting with his group and getting a chance to do actual research in a lab, I changed my graduate path from computational physics to experimental physics and never looked back. Professor Mu's group has always felt like an extended family, where the members worked hard and helped each other without question. I also learned humility in his groupcelebrate the victories in the lab, but be mindful of the people and path that led to that point. I honestly can't begin to express how much I appreciate everything he has done to help me and my family over the years. He has been there through all of the ups and downs in my personal and professional life, and I am honored for the chance to continue to work with him in the future.Professor Richard Haglund accepted me into his group at Vanderbilt after I finished my Master's at Fisk University. I struggled at the beginning while trying to balance course work with research and family, and he gave me some of the best advice I've ever received. He told me that my future was in my hands and that I would fail or succeed based on my own actions. That motivated me to work harder than I had ever worked and is something I still carry with me today.I also want to thank Professor Haglund for instilling within me a deeper appreciation for the elegance of physics, from cascade lasers to perturbation theory. His depth of knowledge and work-life balance are inspiring, and I look forward to working with him in future projects. My mom and dad worked extremely hard to provide a solid foundation for me and my brother. I couldn't ask for better parents. My dad worked to provide for our family, and my mom put her career on hold to stay home with me and my brother. They encouraged us to reach for the stars and to always choose the right path, even if it was the more difficult one. I am who I am today due in large part to the sacrifices, encouragement, and love that my parents provided.
