Amino-functionalized graphene quantum dots: origin of tunable heterogeneous photoluminescence
G. Sandeep Kumar,Rajarshi Roy,Dipayan Sen,Uttam Kumar Ghorai,Ranjit Thapa,Nilesh Mazumder,Subhajit Saha,Kalyan Kumar Chattopadhyay +7 more
TL;DR: Comprehensive theoretical and experimental analysis revealed that newly created energy levels can exist as an interband within the energy gap in functionalized graphene quantum structures yielding excitation dependent tunable PL for optoelectronic applications.
Journal ArticleDOI
ZnSnO3 Nanoparticle-Based Piezocatalysts for Ultrasound-Assisted Degradation of Organic Pollutants
TL;DR: In this paper, a promising alternative of photocatalysis where the strained state of a piezoelectric material is exploited for electrochemical surface reactions under dark conditions is discussed.
Journal ArticleDOI
Photoluminescence and thermoluminescence characterization of Eu3+- and Dy3+ -activated Ca3(PO4)2 phosphor
TL;DR: In this paper, the photoluminescence and thermolumine properties of rare earth-doped polycrystalline Ca3(PO4)2:Eu, Ca3PO4:Dy, CaSO4: Dy and Ca3 PO4 2:DY lattice sites were studied for their X-ray diffraction, thermoluminance (TL) and photolumeinescence (PL) characteristics.
Journal ArticleDOI
White light emitting MgAl2O4:Dy3+,Eu3+ nanophosphor for multifunctional applications.
Karamjyoti Panigrahi,Subhajit Saha,Sumanta Sain,Rituparna Chatterjee,Antika Das,Uttam Kumar Ghorai,Nirmalya Sankar Das,Kalyan Kumar Chattopadhyay +7 more
TL;DR: Detailed investigation of PL properties reveals that Eu3+ ions can be well sensitized by Dy3+ under near-ultraviolet excitation of 351 nm, which indicates that the obtained nanophosphors are highly promising for utilizing in WLED based solid state lighting and self-referencing ratiometric temperature sensor applications.
Journal ArticleDOI
