    Coordination compounds of Europium(III) are excellent materials for a new generation of light emitting devices with high efficiency, easy color tuning, temperature insensitivity, and high stability. Compounds Eu(TTA)3(Ph3PO)2, ...
  • Control of HVPE grown GaN nanostruturing by anodization 
    MONAICO, Ed.; MOISE, C.; MIHAI, G.; ENACHESCU, M.; NIELSCH, K.; URSAKI, V. V.; TIGINYANU, I. M. (Institutul de Fizică Aplicată, AŞM, 2018)
    In this paper, results of a systematic study of morphologies obtained with anodization in HNO3, HCl, and NaCl solutions are presented. It is shown that complex pyramidal structures composed by regions with modulated porosity ...
  • Gold Electroplating as a Tool for Assessing the Conductivity of InP Nanostructures Fabricated by Anodic Etching of Crystalline Substrates 
    MONAICO, E. V.; TIGINYANU, I. M.; URSAKI, V. V.; NIELSCH, K.; BALAN, D.; PRODANA, M.; ENACHESCU, M. (The Electrochemical Society, 2017)
    Electroplating is shown to represent a simple and effective tool for assessing the conductivity of InP nanostructures fabricated by electrochemical etching of InP wafers. A mixture of nanowalls, nanowires and nanobelts was ...
  • Photoluminescent nanocomposite materials based on SBMA copolymer and CdS 
    IOVU, M.; ENACHESCU, M.; CULEAC, I.; VERLAN, V.; ROBU, S.; BOJIN, D.; NISTOR, Iu.; COJOCARU, I. (SPIE, 2015)
    We present experimental results on copolymer-based nanocomposite made of styrene with butyl methacrylate (SBMA) (1:1) and inorganic semiconductor CdS. Thin film composite samples have been characterized by UV-Vis absorption ...
  • Synthesis and optical characterization of Eu(TTA)3(Ph3PO)2 
    BORDIAN, O. T.; VERLAN, V. I.; IOVU, M. S.; CULEAC, I. P.; ZUBAREV, V. E.; BOJIN, D. E.; ENACHESCU, M. (Institutul de Fizică Aplicată al AŞM, 2015)
    Coordination compound tris(thenoyltrifluoroacetonato)bis(triphenylphosphine oxide) europium(III) Eu(TTA)3(Ph3PO)2, where TTA is the thenoyltrifluoroacetonate monoanion (C8H5F3O2S), Ph3PO is triphenylphosphinoxide (TPPO), ...
  • Towards Uniform Electrochemical Porosification of Bulk HVPE-Grown GaN 
    MONAICO, Ed.; MOISE, C.; MIHAI, G.; URSAKI, V. V.; LEISTNER, K.; TIGINYANU, I. M.; ENACHESCU, M.; NIELSCH, K. (The Electrochemical Society, 2019)
    In this paper, we report on results of a systematic study of porous morphologies obtained using anodization of HVPE-grown crystalline GaN wafers in HNO3, HCl, and NaCl solutions. The anodization-induced nanostructuring is ...
  • WO3/WS2 composite materials for gas sensor and energy storage applications 
    URSAKI, V.; GHIMPU, L.; MESTERCA, R.; BRANCOVEANU, O.; PRODANA, M.; ENACHESCU, M.; DIMITRACHI, S.; TIGINYANU, I. (Institutul de Fizică Aplicată, 2018)
    Transition metal binary compounds, especially oxides and chalcogenides, are material of choice for many applications. Particularly, tungsten trioxide (WO3) has been extensively studied due to its outstanding electrochromic ...
