CVD is a newer and much easier method compared to the traditional synthetic diamond growing method, called High Pressure, High Temperature (HPHT) method. HPHT involves apparatus that imitates natural diamond forming conditions that occur in earth’s mantle. Typically, in CVD method, carbon carrier gas is decomposed in a vacuum chamber that crystallizes on a diamond seed, and we get lab grown diamond in couple of weeks in contrast to the natural case which normally takes billion years.</p></div><div class="blog-subtitle" style="box-sizing: border-box; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><h2 style="box-sizing: border-box; margin-top: 20px; margin-bottom: 0.5rem; font-weight: 500; line-height: 1.2; color: rgb(51, 51, 51); font-size: 1.6rem;">From Flaws to Flawless</h2></div><div class="content" style="box-sizing: border-box; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><p style="box-sizing: border-box; margin: 15px 0px; text-align: justify;">Among the various types of CVD process, the MPCVD method is quite popular due to low temperature and pressure condition. Recently, India, specifically Surat has become hub of the Lab Grown Diamond market adopting MPCVD technique to grow LGD. For flawless diamond growth using MPCVD, the key process parameter must be maintained with extremely tight control. In fact, MPCVD diamond often shows low color grade, sometimes brown color at their as grown state due to presence of Nitrogen (N2) element. Recognizing incorporated impurities like N2 or Si may deteriorate the diamond color grade and properties. Hence, it is important to monitor the plasma during the growth process so that any source of nitrogen or other impurities, in the feed gas or from a leakage in the chamber could be eliminated.</p></div><div class="blog-subtitle" style="box-sizing: border-box; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><h2 style="box-sizing: border-box; margin-top: 20px; margin-bottom: 0.5rem; font-weight: 500; line-height: 1.2; color: rgb(51, 51, 51); font-size: 1.6rem;">HORIBA OES tool for Plasma monitoring in LGD</h2></div><div class="content" style="box-sizing: border-box; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><p style="box-sizing: border-box; margin: 15px 0px; text-align: justify;">HORIBA has developed a wide range of optical sensors, based on optical emission spectroscopy (OES).

For example, figure 3 shows emission spectra obtained during the growth from two different diamond growing chambers using HORIBA EV 2.0 HR system. Along with C2 and H2 radicals emission of CN radicals observed in plasma of chamber 2. Spectrum from chamber 1 shows the emission from hydrogen (H) and carbon (C) radicals like Hβ at 457 nm, Hα at 657 nm, CH at 430 nm and C2 in the range of 450- 475 nm &amp; 500-570 nm. Thus, OES is a powerful tool to identify all radicals present in plasma during growth. Seeing the CN emission peak without N2 gas presence confirms leak in the chamber and hence protects the users from wasting time and money. In Figure 3 (b) and (d) show the stability of intensity of C2, H, CH and CN radicals’ emission with respect to time from chamber 1 and 2 respectively.
