Abstract

High quality La₂CaB₁₀O₁₉ single crystals doped with Pr³⁺ ions were grown by means of the top seeded solution growth method. The concentration of Pr³⁺ ions in the starting melt was equal to 4 at%, which in consequence gave single crystals containing 2.5 at% of Pr³⁺ ions, due to small distribution coefficient. The absorption and luminescence spectra were recorded in the wavelength range from 200 to 3000 nm at an ambient temperature of 24 °C and analyzed using the JuddOfelt theory. With the intensity parameters obtained in the present work, the estimated radiative life time of the ³P₀ emitting state is 28 μs. Possible applications of this crystal as a luminophore are discussed.
