“…However, in the present experiment, the capping of the mother solution and the formation of inclusions during the initial stages of growth was completely eliminated by performing improved seeding procedure. 10) Figure 1(d) displays the cut and polished rectangular plates of 1 mol% Fe-doped KTP crystals. The grown crystals show a well-facetted morphology similar to pure KTP crystals without any veils and inclusions.…”

In this paper we report the effect of trivalent ion (Cr and Fe) doping on the ionic conductivity and dielectric properties of selfflux-grown Potassium Titanyl Phosphate (KTiOPO 4 ; KTP) single crystals. Their electrical properties revealed that Cr-and Feion-doped KTP single crystals exhibit a lower ionic conductivity (1-2 orders of magnitude) than that of pure crystal. However, the frequency and temperature dispersion of the ionic conductivity and dielectric constant of Cr-and Fe-ion-doped KTP crystals are almost similar to pure KTP crystals. The measured activation energy indicates the existence of superionic conduction behavior. The incorporation of trivalent ions shifts the optical absorption edge in the UV-VIS spectrum towards the long-wavelength region and increases the optical absorption coefficient of KTP crystals. Vickers microhardness results showed that trivalent ion doping decreases the mechanical strength of pure KTP crystals.

“…Non-linear optical properties of RTP crystals are close to those of KTP but the first are more preferable in some practical applications due to lower electrical conductivity. In the last time a number of investigations concerning with the RTP crystal growth and the study of their properties have been published [4,5]. In Ref.…”

“…The larger is this ratio, or the richer (in rubidium) is the flux, the higher is the rubidium content in the crystal, which is manifested in its higher Curie temperature. The most widely used solvent for growth of RTP crystals from self-fluxes is Rb 6 P 4 O 13 , corresponding to the ratio [Rb]/[P] ¼ 1.5 [1,[9][10][11], which yields crystals of moderate Curie temperatures. Tangibly higher Curie temperatures, implying better rubidium stoichiometry, are obtained with rubidium phosphate solvents of larger [Rb]/[P] ratios, such as Rb 4 P 2 O 7 , especially for growth on [1 0 0]-oriented seeds [7].…”
