Random laser rn ZnO powder pumped by picosecond pulses
VNU Journal of Science: Mathematics - Physics - Tập 27 Số 1 - 2011
Abstract. We report ow studies of random laser from ZnO powder at room temperature. The powder of ZnO colloidal spheres was synthesized by hydrolysis of Zinc acetate dehydrate. The random lasing around 380nm was produced from a layer of the ZnO powder pumped by the third harmonics (:SSnm) of a picosecond mode locked Nd:YAG laser (1L2143B-- Ekspla). Above a pump threshold, discrete lasing modes of ... hiện toàn bộ
Predict optical properties of Dy3+ ions doped double potassium gadolinium fluoride crystal from absorption spectra
VNU Journal of Science: Mathematics - Physics - Tập 28 Số 2 - 2012
Abstract. Double potassium gadolinium fluoride crystal doped with 5.0 mol % of Dy3+ ions (K2GdF5:Dy3+) was synthesized under hydrothermal condition. The absorption, luminescence spectra and lifetime of K2GdF5:Dy3+ sample were measured at room temperature. Judd – Ofelt (JO) theory is used to study the spectral properties and to calculate the radiative transition probabilities. The prediced branchin... hiện toàn bộ

Epitaxial-like Growth of Solution-processed PbZr0.4Ti0.6O3 Thin Film on Single-crystal Nb-doped SrTiO3 Substrate
VNU Journal of Science: Mathematics - Physics - Tập 33 Số 4 - 2017
Trinh Bui Nguyen Quoc
PbZr0.4Ti0.6O3 (PZT) thin films have been conventionally fabricated on traditional silicon substrates with a platinum bottom electrode; however, as a consequence of unit cell mismatch, the films are difficult to form as an epitaxial-like growth. Hence, PZT films deposited on single-crystal niobium doped SrTiO3(111) substrates (Nb:STO) are promising to solve this issue thanks to the similar perovsk... hiện toàn bộ
Preliminary Study on Alternative Reflectors for LOTUS Reactor
VNU Journal of Science: Mathematics - Physics - Tập 39 Số 2 - 2023
Bui Thi Hong, Thanh Mai Vu, Donny Hartanto
LOTUS reactor - a compact lead-cooled fast reactor is currently being studied to generate 200 MWth of capacity and operate for 20 years without refueling for the floating nuclear power plant (FNPP) application. Therefore, it would be a big advantage to achieve a long operation without refueling. However, a small reactor usually has a higher neutron leakage, and a good neutron reflector is essentia... hiện toàn bộ
On the Perron Effect for Exponential Stability of Differential Systems on Time Scales
VNU Journal of Science: Mathematics - Physics - Tập 33 Số 4 - 2017
Nhien Le
In 2007, N. H. Du and L. H. Tien [1] shown that the exponential stability of the linear equation on time scales implies the exponential stability of the suitable small enough Lipchitz perturbed equation. In this paper, we shall prove that if the perturbation is arbitrary small order 1 then the above argument is not true which is called Perron effect.
