The excitation and emission bands also broaden with codoping due to presence of these additional energy levels. Therefore Ca codoping in Gd<sub>2</sub>SiO<sub>5</sub> crystals decreases the scintillation decay very strongly and has a strong adverse affect on scintillation light yield, different from the effect in other members of the oxyorthosilicate family such as Lu<sub>2</sub>SiO<sub>5</sub> and Y<sub>2</sub>SiO<sub>5</sub>.</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Keywords</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>X-ray detection; calcium; doping; gadolinium compounds; gamma-ray detection; photoluminescence; solid scintillation detectors; Ca codoping; Gd<sub>2</sub>SiO<sub>5</sub>:Ce,Ca; X-ray detector; additional energy levels; emission bands; excitation bands; gamma radiation detector; nonradiative energy transfer; oxyorthosilicate family; photoluminescence properties; scintillation decay; scintillation light yield; temperature dependence; Absorption; Calcium; Crystals; Energy exchange; Energy states; Ions; Temperature dependence; <formula formulatype=${rm Gd}_{2}{rm SiO}_{5}$ (GSO); Calcium; cerium; co-doping; photoluminescence;
