Jade samples show broad band luminescence from green to red, which, using lifetime-resolved CL, reveals seven overlapping emissions, of which two are dominant. Green emission obtained using spatially resolved CL was associated with Mn2+ and emission bands centered near at 480 and 530nm were attributed to 3P0-3H4 and 1D2-3H4 transitions of Pr3+, respectively. Different shifts of the peak-wavelengths for 326 and 565nm were observed with varying jade compositions. The incorporation of the larger K ion causes non-linear variations of the cell dimensions and therefore changes in the Fe-O band distance. We suggest that stress of the jade structure can be linked to the luminescence emission at 326nm. Raman spectra have also been recorded in order to provide an unequivocal identification of the type of jade. The mechanism for the luminescence of the jade is considered. © 2011 Elsevier Ltd.EnglishCathodoluminescenceManganeseManganese compoundsRaman spectroscopyThermoluminescencealuminum oxidebarium oxidecalcium oxidechromic oxideironiron oxidemanganese oxidemetal oxideoxygenphosphorus pentoxidepotassium ionpotassium oxidesilicatesilicon dioxidesodium oxidestrontium oxidetitanium dioxideunclassified drugBroad bandsCell dimensionsEmission bandsGreen emissionsJadeLuminescence emissionNon-linear variationRadioluminescenceRamanRaman characterizationRaman spectraSpatially resolvedarticlecathode luminescencecell sizechemical structurecontrolled studyluminescencepriority journalradiation measurementradioactivityradioluminescenceRaman spectrometrythermoluminescenceTurkey (republic)X ray diffractionX ray fluorescenceSilicate mineralsArticle10.1016/j.apradiso.2011.05.011
