The X-ray powder diffraction analysis, photoluminescence excitation and emission spectra, thermal quenching, and decay curves were applied to investigate the phase structure, luminescence, and thermal stability properties. Under the excitation of 351 nm, the emission of Li<SUB>3</SUB>Gd<SUB>3</SUB>Te<SUB>2</SUB>O<SUB>12</SUB>:0.02Dy<SUP>3+</SUP> sample centered at blue (488 nm) and yellow (580 nm), corresponding to <SUP>4</SUP>F<SUB>9/2</SUB>–<SUP>6</SUP>H<SUB>15/2</SUB> transition and <SUP>4</SUP>F<SUB>9/2</SUB>–<SUP>6</SUP>H<SUB>13/2</SUB> transition, respectively. The optimum dopant concentration of Dy<SUP>3+</SUP> ions in Li<SUB>3</SUB>Gd<SUB>3</SUB>Te<SUB>2</SUB>O<SUB>12</SUB>:<I>x</I>Dy<SUP>3+</SUP> was around 2 mol%. The thermal-quenching temperature was above 500 K for Li<SUB>3</SUB>Gd<SUB>3</SUB>Te<SUB>2</SUB>O<SUB>12</SUB>:0.02Dy<SUP>3+</SUP>. The tunable white light and correlated color temperature can be achieved in the present Li<SUB>3</SUB>Gd<SUB>3</SUB>Te<SUB>2</SUB>O<SUB>12</SUB>:<I>x</I>Dy<SUP>3+</SUP> phosphors by adjusting the yellow to blue intensity ratio based on the concentration of Dy<SUP>3+</SUP> ions. The fabricated warm white LED indicates the phosphor could be a single-component white light-emitting phosphor for UV light-emitting diodes.</P>
Recent trends in therapeutic strategies for repairing endometrial tissue in intrauterine adhesion
Junyan Ma,Hong Zhan,Wen Li,Liqi Zhang,Feng Yun,Ruijin Wu,Jun Lin,Yangyang Li 한국생체재료학회 2021 생체재료학회지 Vol.25 No.4
Intrauterine adhesion (IUA) is a common gynaecological disease that develops from infection or trauma. IUA disease may seriously affect the physical and mental health of women of childbearing age, which may lead to symptoms such as hypomenorrhea or infertility. Presently, hysteroscopic transcervical resection of adhesion (TCRA) is the principal therapy for IUAs, although its function in preventing the recurrence of adhesion and preserving fertility is limited. Pharmaceuticals such as hormones and vasoactive agents and the placement of nondegradable stents are the most common postoperative adjuvant therapy methods. However, the repair of injured endometrium is relatively restricted due to the different anatomical structures of the endometrium. Recently, the treatment outcome of IUAs has improved with the advancement of hysteroscopic techniques. In particular, the application of bioactive scaffolds combined with tissue engineering technology has proven to have high therapeutic potential or endometrial repair in IUA treatment. Herein, this review has summarized past therapeutic strategies, including postoperative adjuvant therapy, cell or therapeutic molecular delivery therapy methods and bioactive scaffoldbased tissue engineering methods. Therefore, this review presented the recent therapeutic strategies for repairing endometrium treatment and pointed out the issues of clinical concern to provide alternative methods for the management of IUAs.
