Growth of Nd3+ doped LiNbO3 crystals using Bridgman method and its spectral properties

Abstract

The growth of Nd 3+ doped lithium niobate crystals using Bridgman method has been reported in this paper. By means of the optimum conditions such as proper feed materials, sealed platinum crucibles, growth rate of 1-1⋅5 mm/h and temperature gradient of 30-35°C/cm across the solid-liquid interface under the furnace temperature of 1300°C, single crystals containing Nd 3+ ion with 0⋅54 mol% concentration were obtained. X-ray diffraction and ICP-AES were used to characterize the crystals and its composition. The absorption, emission and fluorescence lifetime are also measured. Based on the Judd-Ofelt theory, we obtained the optical parameters of the crystal such as the luminescent quantum efficiency, the radioactive lifetimes, the branching ratios and the emission cross-section.

X-ray-induced Luminescence Properties of Nd-doped GdVO4

“…The intensity of the emission peak around 1060 nm was the highest, and this emission is commonly used in laser applications. (37) These emissions were due to the electronic transitions of Nd 3+ 4 F 3/2 → 4 I 9/2 (900 nm), 4 F 3/2 → 4 I 11/2 (1060 nm), and 4 F 3/2 → 4 I 13/2 (1320 nm). (32,38,39) The X-ray-induced scintillation decay time profiles of the Nd-doped samples are illustrated in Fig.…”

GROWTH OF YB³⁺ DOPED LiNBO₃ CRYSTALS USING LASER HEATED PEDESTAL GROWTH METHOD

“…Since the early work of Verneuil and Czochralski on crystal growth (Wang et al, 2009;Doiphode and Psingh, 2012), scientific researchers have been mainly concentrated on the improvement of growth techniques in order to obtain crystals of high performance. The growth techniques of single crystals are limited to few methods, because of the complexity of the systems and their costs.…”
