Subsolidus phase relations in CaO–In2O3–B2O3 system and crystal structure of CaInBO4

Crystal and local atomic structure of MgFeBO4 , Mg0.5 Co0.5 FeBO4 and CoFeBO4 : Effects of Co substitution

“…A variety of heterometallic warwickites has been synthesized to date; MgGaBO 4 , MgFeBO 4 , MgVBO 4 , MgCrBO 4 , CoFeBO 4 , CoCrBO 4 , NiFeBO 4 , Fe 1.91 V 0.09 BO 4 , CaInBO 4 are just some representative examples. An important feature of mixed‐metal warwickites is the random distribution of metal ions among nonequivalent metal sites giving rise to random short‐range AF interactions.…”

Site-occupancy scheme in disordered Ca3RE2(BO3)4: a dependence on rare-earth (RE) ionic radius

“…In the case of SSR samples (except for RE = Dy), consecutive melting was found to be a favourable factor for successful synthesis -otherwise, REBO 3 often appeared as a main crystalline phase, indicating the failure of the synthesis. The most likely minor phases (up to several weight percent) in samples synthesized by SSR are of RECa 4 O(BO 3 ) 3 [of the Ca 5 (BO 3 ) 3 F type] and RECa(BO 3 )O; the latter refers to compounds of the warwickite structure, which has been reported for calcium borates only for RE = Sc (Ma et al, 2017) and Y (Zhang et al, 2001), and for InCa(BO 3 )O (Li et al, 2012). The initial identification of these impurity phases was based on the layout of the diffraction peaks and was confirmed by Rietveld refinement.…”

Luminescent properties and performance tune of novel red-emitting phosphor CaInBO4: Eu3+

“…Search for new luminescent materials in borates, attentions have been paid to MO-RE 2 O 3 eB 2 O 3 (M ¼ alkaline-earth-metal, RE ¼ rare earth elements) ternary systems, with plenty of phosphor host with outstanding luminescent properties, for instance, YBO 3 [11,12], MgGdB 5 O 10 [13], and CaYBO 4 [14,15]. In 2012, the subsolidus phase relations of CaOeIn 2 O 3 eB 2 O 3 system and the new borate CaInBO 4 (CIBO) were first reported by our group [16]. CIBO crystallizes in the orthorhombic space group Pnma (No.…”
